On 9 October 2019, the Turkish Armed Forces (TAF) and the Syrian National Army (SNA) launched an offensive against the Syrian Democratic Forces (SDF) and later it involved the Syrian Arab Army (SAA) in northern Syria. It was code-named the Operation Peace Spring (Turkish: Barış Pınarı Harekâtı) by Turkey.

On 6 October 2019, the Trump administration ordered American troops to withdraw from northeastern Syria, where the United States had been supporting its Kurdish allies. The military operation began on 9 October 2019 when the Turkish Air Force launched airstrikes on border towns. The conflict resulted in the displacement of over 300,000 people and has caused the death of more than 70 civilians in Syria and 20 civilians in Turkey. Human rights violations have also been reported. Amnesty International stated that it had gathered evidence of war crimes and other violations committed by Turkey and Turkish-backed Syrian forces who are said to "have displayed a shameful disregard for civilian life, carrying out serious violations and war crimes, including summary killings and unlawful attacks that have killed and injured civilians".

According to Turkish President Recep Tayyip Erdoğan, the operation was intended to expel the SDF—designated as a terrorist organization by Turkey "due to its ties with the Kurdistan Workers Party (PKK)", but considered an ally against ISIL by the Combined Joint Task Force – Operation Inherent Resolve—from the border region as well as to create a 30 km-deep (20 mi) "safe zone" in Northern Syria where some of the 3.6 million Syrian refugees in Turkey would resettle. As the proposed settlement zone is heavily Kurdish demographically, this intention has been criticized as an attempt at ethnic cleansing, a criticism rejected by the Turkish government who claimed they intended to "correct" the demographics that it alleges have been changed by the SDF.

The Turkish operation was met with mixed responses from the international community, including condemnations as well as support for the operation for the settlement of refugees in Northern Syria. Although Turkey claimed self-defense, according to international law experts it is an illegal use of force. While originally acknowledging Turkey's "right to defend itself", on 15 October, Russia hardened its position against the operation and deployed troops. Ten European nations and Canada imposed an arms embargo on Turkey, while the U.S. imposed sanctions on Turkish ministries and senior government officials in response to the offensive in Syria. The Assad-led Syrian government initially criticized the SDF for the Turkish offensive, accusing it of separatism and not reconciling with the government, while at the same time also condemning the foreign invasion of Syrian territory. However, a few days later, the SDF reached an agreement with the Syrian government, in which it would allow the Syrian Army to enter the SDF-held towns of Manbij and Kobanî in an attempt to defend the towns from the Turkish offensive. Shortly thereafter, Syrian state broadcaster SANA announced that Syrian Army troops had started to deploy to the country's north. Turkey and the SNA launched an offensive to capture Manbij on the same day.

On 17 October 2019, U.S. Vice President Mike Pence announced that the U.S. and Turkey agreed on a deal in which Turkey would agree to a five-day ceasefire in Syria in return for a complete withdrawal by the SDF from its positions on the Syria-Turkey border. On 22 October 2019, Russian President Vladimir Putin and Turkish President Recep Tayyip Erdoğan reached a deal to extend the ceasefire by 150 additional hours if the SDF would move 30 kilometers away from the border, as well as from Tal Rifaat and Manbij. The terms of the deal also included joint Russian–Turkish patrols 10 kilometers into Syria from the border, except in the city of Qamishli. The new ceasefire started at 12pm local time on 23 October. The captured area remains part of the Turkish occupation of northern Syria.

Background

Turkish motives

Turkey has complained about a supposed presence of PKK-related forces at its southern border since 2012, when the first YPG pockets appeared during the Syrian Civil War. Following the 2014 Siege of Kobanî and the expansion of YPG/SDF forces and administration, Erdoğan's government considered the force a national security threat. The 2013–2015 peace process collapsed in July 2015, resulting in a war between PKK and Turkish forces. Like other regions in southeast Turkey, regions north of the border with Syria have seen numerous PKK-related deaths. According to a Crisis Group death toll analysis based upon Turkey government and Turkish media publications, the border regions north of SDF-controlled areas had 8 Turkey security forces and 5 civilians killed in PKK-related violence in 2018 and 2019 prior to the offensive. The Şırnak region had 26 security forces and 6 civilian deaths over the same period. Crisis Group did not specify if "PKK-related" deaths are linked to Syria's YPG and SDF, or from Turkey or Iraqi PKK.

Recent increase in jobless rate and electoral collaboration of opposition parties lead to significant AKP defeats in the 2019 Istanbul mayoral election, signaling difficulties for the leadership party. Military operations are known to boost nationalism and Turkey executive's popularity. It is also seen as an effective way to break apart opposition alliances, between pro-Kurdish and pro-peace representatives actively criminalized by the government, and other opposition parties who are faced with the dilemma of betraying the informal political alliance in order to showcast popular patriotism. Moreover, another driver for the Turkish operation into Syria is the domestic politics involving the 3.6 million Syrian refugees residing in Turkey—the highest number of refugees hosted by any country—which has led to increasing public dissatisfaction and therefore public support and pressure for intervention. The negative sentiment against refugees among the Turkish electorate allows Erdogan and his AKP to benefit from moving refugees back to Syria. According to CrisisGroup analysis, this political strategy has cost AKP half of its conservative Kurds' supports since 2015.

Immediate context rebuff

Turkey and the United States struck a deal in August 2019 after months of Turkish threats to unilaterally invade northern Syria. The United States viewed the Syrian Democratic Forces as one of its key allies in the military intervention against ISIL in Syria, while Turkey viewed the group as an extension of the Kurdistan Workers Party (PKK), which it considers a terrorist group. The agreement established the Northern Syria Buffer Zone, which aimed to reduce tensions by addressing Turkey's security concerns with monitoring and joint patrols, while still allowing the NES to retain control over the areas that it had under its control at that time. The agreement was received favorably by the U.S. and SDF, but Turkey was generally dissatisfied with it. Turkey's dissatisfaction led to numerous Turkish efforts to expand the area covered by the buffer zone, secure Turkish control over parts of it, or relocate millions of refugees into the zone, with all of these efforts failing in the face of firm SDF resistance and American ambivalence.

Despite the official start of U.S.-Turkish ground patrols, the dismantling of SDF fortifications, and the withdrawal of YPG units from parts of the buffer zone, tensions continued to rise as Turkey levied yet more demands on the SDF—all of which the SDF denied, as they felt they had accepted a harsh compromise by permitting Turkish troops to take part in joint patrols with their American counterparts in northern Syria. Turkey's dissatisfaction with the status quo of the agreement grew into open hostility, with the Turkish president openly posing an ultimatum against the SDF. The ultimatum was ignored by the group and Turkey declared its "deadline" to have expired at the start of October that same year.

Prelude

Preparations for the offensive began in July 2019, with the final preparation in October starting with the withdrawal of American forces from positions near the Turkish border. This withdrawal followed a phone call between Turkish President Recep Tayyip Erdoğan and United States President Donald Trump, wherein Erdoğan informed President Trump that Turkey would "soon" be carrying out a planned military offensive into Kurdish-administered northern Syria against SDF-held areas east of the Euphrates river. While the U.S. government stated it did not support the Turkish-led offensive, the White House also announced on 6 October 2019 that it would not interfere, and would withdraw all personnel in the area to avoid a potential U.S.-Turkish standoff; U.S. Secretary of State Mike Pompeo denied that this amounted to giving Turkish forces a "green light" to attack the SDF while a spokesman for the SDF called the U.S. withdrawal a betrayal. The US also reportedly cut off aid to the SDF in order to avoid arming them against a NATO ally.

On 8 October 2019, the Turkish military reportedly bombed a convoy of weapons vehicles heading from Iraq into Syria destined for the SDF. However the SDF did not retaliate and no casualties were reported as a result of the air strike. On the same day Russian special forces opened a crossing on the Euphrates river between areas held by the Syrian Government and SDF in the Deir ez-Zor Governorate. While the SDF stated that the Syrian military was preparing to enter the city of Manbij in northeastern Aleppo, the Syrian government responded by saying the build up of the Syrian military near Manbij was being done in order to prevent the Turkish military from entering the city. On the same day, Turkish forces shelled Ras al-Ayn and fired machine guns in the vicinity of the city.

Operation timeline

9 October 2019

The operation began on 9 October 2019, with Turkish airstrikes and howitzers targeting the SDF-held towns of Tell Abyad, Ras al-Ayn where thousands of people were reported to have fled the town, Ayn Issa and Qamishli. The start of the incursion was symbolic, as it was the 21st anniversary of the PKK leader Abdullah Öcalan's expulsion from Syria in 1998 by the government of Hafez al-Assad.

In response to the cross-border shelling, SDF's spokesman stated that Turkey was targeting civilians. Six rockets were later launched at the Turkish city of Nusaybin as a response by the YPG, and two reportedly hit the Turkish town Ceylanpınar. The SDF also announced in response to the start of the Turkish operation they would be halting anti-ISIL operations, and that two civilians had been killed. In response to the airstrikes, the SDF called upon the United States to establish a no-fly zone over northern Syria.

During the day, under pressure from Congressmen and public opinion, Trump sent a letter to Erdoğan urging him to come to an agreement with General Mazloum and avoid any further conflict. Enclosed within the letter was a copy of a letter written by the General detailing concessions the General would be willing to make. Trump also threatened economic retaliation, stating "I don't want to be responsible for destroying the Turkish economy." According to official sources, Erdoğan took offense to the letter, reportedly throwing it in the trash. The White House released the letter to the press on 16 October, receiving wide ridicule.

Ground offensive

By the end of the day, the Turkish military announced that the ground phase of the operation had begun from three points including Tell Abyad.

10 October 2019

Before dawn on the morning of 10 October 2019, the Turkish military officially began the ground offensive against the SDF; they also announced they had hit 181 targets in northern Syria, and 14,000 rebels backed by Turkey, including Ahrar al-Sharqiya rebel group, Sultan Murad Division, and Hamza Division, are also taking part in the Turkish-led offensive. According to a research paper published this October by the pro-government Turkish think tank SETA, "Out of the 28 factions , 21 were previously supported by the United States, three of them via the Pentagon’s program to combat DAESH. Eighteen of these factions were supplied by the CIA via the MOM Operations Room in Turkey, a joint intelligence operation room of the 'Friends of Syria' to support the armed opposition. Fourteen factions of the 28 were also recipients of the U.S.-supplied TOW anti-tank guided missiles."

The SDF said they repelled a Turkish advance into Tell Abyad. Later during the day, clashes reportedly broke out between the SDF and Turkish-aligned forces near al-Bab. Turkish-led forces made advances around the area of Tell Abyad and captured the villages of Tabatin and Al-Mushrifah. By nightfall Turkish Armed Forces declared control of 11 villages. As fighting went on around Tell Abyad, the Syrian National Army announced it captured the villages of Mishrifah, Al-Hawi, Barzan, Haj Ali and a farm east of the city. During Turkish air strikes during the fighting, SDF stated that the Turkish air force hit a prison that was holding captured ISIL fighters. Turkish media reported in the late evening that 174 SDF fighters were killed, wounded or captured.

Turkish President Recep Tayyip Erdoğan stated that day that 109 SDF fighters had been killed in the operation as well as an unspecified number of fighters wounded and captured. In a speech to lawmakers from Erdoğan's AKP, the Turkish president also threatened to flood Europe with 3.6 million refugees if European nations continued to criticize the military operation, in particular if they labelled it an invasion.

70,000 people fled from border towns in the SDF following Turkish bombardment.

According to Turkey's Ministry of National Defence, one Turkish soldier was killed by the YPG.

11 October 2019

Two journalists were wounded in Nusaybin, when the building they were filming from came under fire from Qamishli across the border by SDF fighters. The incident was broadcast live on Turkish TV channels, according to Turkish sources.

Three civilians were killed in Suruc by SDF shelling. In response to the attack, Turkey shelled YPG positions in Kobani, across the border from Suruç. Eight more civilians were killed later in the day in Nusaybin and 35 were injured by SDF mortar attack, raising the total civilians killed by SDF shelling in Turkey to 18, according to Turkish sources.

Seven civilians were killed in Syria by Turkish forces in the Tal Abyad area including three killed by Turkish snipers according to SOHR.

As reported on this day, according to the Turkish Ministry of National Defence, a total of 399 SDF fighters were killed, captured or wounded since the start of the Turkish military operation.

The Syrian National Army stated to have taken the village of Halawa which is southeast of Tell Abyad. TAF and SNA announced the capture of Tell Halaf later in the day and released a video from inside the town.

In the city of Qamishli, a suspected ISIL car bomb killed five civilians, while a reported Turkish artillery strike hit a nearby prison, and five suspected ISIL members, previously detained in SDF custody, escaped according to SDF.

In the city of Kobanî, the area immediately around a U.S. special forces base experienced heavy shelling by Turkish artillery; the U.S. troops did not retaliate, but withdrew after the shelling ended. Turkey responded by denying that it targeted the U.S. base, instead stating that it had fired upon SDF positions. The Pentagon further raised concerns that the Turkish Army deliberately "bracketed" US Forces stationed in Kobanî with artillery fire. According to Turkish Defense Minister, the mortar attack targeting the town of Suruç earlier in the day was deliberately launched 1000 meters from the US base in Kobanî by SDF to avoid Turkish retaliation and the attack was in response.

The BBC reported that 100,000 people have fled their homes in northern Syria. The Kurdish Red Crescent (Heyva Sor) said there had been 11 confirmed civilian deaths so far. Turkey's military confirmed a soldier's death, and said three others had been wounded.

Turkey's Ministry of National Defence announced that three more soldiers had been killed by the YPG, two of which were killed in a mortar attack on a Turkish military base in a Turkish-occupied part of Syria. This brought the total number of Turkish soldiers killed in the operation to four. The SOHR reported that the actual number of Turkish soldiers killed in the operation was six. Later in the day, the SOHR reported that at least 12 Turkish border guards were either killed or wounded in a confrontation with the SDF in Kobanî.

12 October 2019

Turkish Armed Forces and Syrian National Army said they reached the M4 highway, 32 km (20 mi) deep into Syrian territory and effectively cutting the supply line between Manbij and Qamishli. SNA also said they captured 18 villages close to M4 highway in eastern Raqqah.

Turkish interior minister Süleyman Soylu announced that nearly 300 mortar shells had been fired at Mardin Province by the SDF since the start of the operation.

Around 12:00 (UTC+03:00), the TAF and SNA stated they had captured Ras al-Ayn, but the SDF denied that Turkey had taken control of the city.

Turkish-backed members of Islamist militia Ahrar al-Sharqiya executed Hevrin Khalaf, Secretary General of the Future Syria Party. Nine civilians, including Khalaf, were executed by the Ahrar al-Sharqiya fighters at a roadblock on the M4 highway south of Tal Abyad. Turkish news source Yeni Safak reported that Khalaf was "neutralized" in a "successful operation" against a politician affiliated with a "terrorist" organization. Her execution was widely described by Western sources as a war crime under international law. A spokesman for Ahrar al-Sharqiya meanwhile announced that she was killed for being "an agent for U.S. intelligence".

A Bellingcat video solidly traces the killings to rebels backed by Turkey Ahrar al-Sharqiya.

13 October 2019

Turkish Armed Forces and Syrian National Army announced the capture of the town of Suluk, located in Tell Abyad District, in the early morning. The SOHR confirmed that the Turkish forces and SNA had taken full control of Suluk, and clashes were nearing towards Ayn Issa. The SOHR also reported that pro-Turkish forces had targeted an ambulance in the Tell Abyad area which remains missing.

The SOHR also reported that the SDF was able to regain almost all control over the contested city of Ras al-Ayn after a counterattack.

Tell Abyad captured and M4 highway cut by Turkey and SNA

Turkish Armed Forces and Syrian National Army announced in the afternoon they had captured the center of Tell Abyad. Turkish Armed Forces and Syrian National Army fully captured Tall Abyad late in the afternoon according to the SOHR. Turkish Armed Forces and Syrian National Army also cut the M4 highway according to SOHR. Turkish sources also reported that SDF shelling towards Jarablus had killed 2 Syrian civilians.

In light of the pro-Turkish forces advance on Ayn Issa, the SDF stated that 785 ISIL-linked people had escaped from a detention camp in the area, SDF also stated the escapees received assistance of the pro-Turkish forces and Turkish airstrikes. In contrast, Turkey stated that the SDF released ISIL prisoners at the Tell Abyad prison before the arrival of Turkish forces. This statement was supported by U.S. President Donald Trump, but opposed by senior U.S. officials who stated that Turkish-backed Free Syrian Army (FSA) forces were the ones freeing ISIL prisoners.

United States Secretary of Defense Mark Esper said that US was planning to evacuate all 1,000 remaining soldiers from northern Syria. US also informed SDF of its intention to withdraw from military bases in Manbij and Kobanî and had already evacuated from Ayn Issa according to SOHR and The Washington Post.

Syrian government–SDF deal

Shortly after the capture of Tall Abyad by Turkey and SNA, a deal between the Syrian government and SDF was reached whereby the Syrian Army would be allowed to enter the towns of Kobanî and Manbij in order to deter a possible Turkish military offensive in those areas.

Later an advisor to leader of AKP Recep Tayyip Erdoğan, Yasin Aktay, said there could be conflict between the two armies, if the Syrian government tries to enter northeastern Syria.

SDF commander-in-chief Mazloum Abdi said he was willing to ally with the Syrian government for the sake of saving the Kurdish population in Northern Syria from what he called a genocide.

14 October 2019

Russian and Syrian forces were reported to have been deployed at the front line between areas controlled by the Manbij Military Council and Euphrates Shield groups respectively, with further deployments to take place along the Syrian-Turkish border. In addition, the SOHR reported that the U.S. forces in the region were attempting to hinder the Russian and Syrian deployments in the region.

The SOHR reported that violent clashes had continued in Ras Al-Ayn and its countryside at the border strip, where the Turkish forces were attempting to encircle the city completely and to cut off the road between Ras Al-Ayn and Tal Tamr, under a cover of artillery shelling and airstrikes with the purpose of taking control of the city by 15 October. Turkish aerial and ground bombardment were reported to have occurred in the border town Al-Darbasiyyah targeting civilian houses which caused 4 reported injuries of medical personnel as per the SOHR.

Turkish President Recep Tayyip Erdoğan told a press conference that Turkey had received a positive response from Russia on Kobani and that Turkey was at the execution phase of its Manbij decision. Turkish Armed forces deployed additional troops to Manbij frontline as of the previous night according to Turkish sources. Turkish Minister of National Defence Hulusi Akar said that Tal Abyad and Ras al-Ayn were under Turkish control and that works were ongoing for the whole region.

The Syrian Army reportedly deployed to the town of Al-Thawrah, as well as Ayn Issa, Tell Tamer and as close as 6 km from the Syria–Turkey border. It also took over the 93rd Brigade Headquarters just south of Ayn Issa, as well as Al-Jarniyah to the east of the Euphrates. The Syrian Army further reported taking control of the Tabqa Dam. The Syrian flag was reportedly raised for the first time in years in several towns and villages in the Al-Hasakah Governorate, such as the city of Al-Yaarubiyah.

Jarabulus Military Council was reportedly to have targeted a vehicle south of Jarabulus by a guided missile leaving 2 persons dead in conjunction with an assassination that targeted members of Turkey-loyal factions south of Azaz.

Turkish Armed Forces and Syrian National Army launched a military operation to capture Manbij in the late afternoon. Turkish Armed Forces and Syrian National Army captured 3 villages in the Manbij countryside shortly after the launch of the operation according to Turkish sources. At the same time, Syrian state media stated that the Syrian Army had started entering the town.

Announcement of total U.S. withdrawal from north Syria

Later in the day, U.S. President Donald Trump announced that all U.S. personnel would withdraw from Syria except those in Al-Tanf base.

15 October 2019

The SOHR reported that a counterattack was carried out by the SDF in the outskirts and western countryside of Ras al-Ayn city, and managed to achieve an advancement in the area recovering 3 areas lost previously.

2 civilians were killed and 12 were wounded in Kızıltepe, Turkey after an SDF mortar attack according to Turkish sources.

Turkish President Erdoğan, speaking at the Turkic Council in Baku, said: "We are now announcing the establishment of a safe area 444 km from west to east and 32 km from north to south, to which the refugees in our country will return." President Erdoğan also said a total of 1,000 square kilometres (390 sq mi) had been captured by TAF and SNA since the start of the operation. President Erdoğan also said a Turkish soldier was killed in Manbij by Syrian Army artillery fire and that there was an intense retaliatory fire for the attack which made the regime pay a heavy price.

Syrian Army forces started entering the town of Manbij according to SOHR, but were blocked by US troops when trying to enter Kobani according to SOHR, which resulted in the convoy's return to Manbij. Syrian Army forces also entered Al-Thawrah according to Syrian government media. Later, Erdoğan told that Syrian Government troops entering Manbij is "not negative" and adding "as long as terrorists in the area are cleaned".

16 October 2019

Villages around the M4 in Jazira province were reportedly shelled by the TAF at dawn while shelling and clashes had caused power outages and a water shortage in the city of Al-Hasakah, the latter of which returned after 5 days since it had been cut off, as per a SOHR report. The SOHR also reported that clashes continued to the west of Ayn Issa as the SDF attempted to launch a counterattack where they were able to successfully regain 2 locations. Clashes had also broken out within the SDF-controlled camp in Ayn Issa between families of ISIL members and displaced civilians which resulted in 2 deaths, as per the SOHR report.

Heavy shelling and airstrikes by the TAF were reported in Ras al-Ayn with heavy fighting on the ground according to SOHR. The SOHR further reported that Turkish forces and allied factions had launched a wide scale offensive and managed to advance into parts of the Ras al-Ayn city. Turkish President Erdoğan announced that Turkey controlled over 1200 square kilometers area since start of the operation.

The Russian military deployed near Kobani on 16 October in the afternoon after crossing Qara Cossack bridge from Manbij to the east of Euphrates according to SOHR. The SOHR also reported that the Syrian Army had completed its deployment in Ayn Issa, north of Raqqa. The Syrian Army also reportedly entered the city of Kobanî at nightfall. This was precipitated by the sudden advance of the Syrian National Army towards the Kurdish-held border city.

U.S. army withdrawal from its military bases

US forces withdrew and destroyed its former air base, south of Kobanî. The airbase was the largest U.S. base in Syria, capable of landing C-130 as well as C-17 heavy transport planes.

17 October 2019

TAF and SNA forces completely besieged and captured half of Ras al-Ayn after getting around the town and cutting off the roads leading to it amid heavy clashes according to SOHR.

Turkish Interior Minister Süleyman Soylu stated that over 980 mortar shells and rockets were launched at Turkey by SDF since the start of the operation killing 20 civilians.

120-hour ceasefire

On 17 October 2019, US Vice President Mike Pence and Turkish President Recep Tayyip Erdoğan reached a deal to implement a 120-hour cease-fire for Turkey's operation in northern Syria to allow SDF to withdraw from a designated safe zone, spanning from the Turkey-Syria border to 20 miles (32 km) south. Mike Pence stated that once the military operation completely stops all sanctions imposed on Turkey by the United States would be lifted and there would be no further sanctions. According to a US statement, the safe zone would be "primarily enforced by the Turkish Armed Forces". This ceasefire deal was described as another US betrayal of the Kurds and a Kurdish surrender to Turkey by several US commentators and officials.

Turkish Foreign Minister Mevlüt Çavuşoğlu stated that it was not a ceasefire but a temporary pause to allow SDF to withdraw from the designated safe zone, after which if completed the operation would end and if not the operation would continue. The SDF commander Mazloum Abdi said that they accepted the ceasefire agreement only in the area between Tall Abyad and Ras al-Ayn.

The Syrian Kurdish politician Salih Muslim stated that "Our people did not want this war. We welcome the ceasefire, but we will defend ourselves in the event of any attack … Ceasefire is one thing and surrender is another thing, and we are ready to defend ourselves. We will not accept the occupation of northern Syria."

During the ceasefire

18 October 2019

Cautious calm prevailed at the east of Euphrates on 18 October according to SOHR with minor clashes in besieged Ras al-Ayn. The SDF claimed that Turkey was violating the ceasefire and of shelling civilian areas of Ras al-Ayn. An unnamed US official said the following day that Turkish backed forces had violated the ceasefire, and the SDF had stopped fighting.

Turkey announced it aimed to establish 12 "observation posts" in its safe zone, with President Erdoğan stating that Turkey will respond if the Syrian government "makes a mistake".

19 October 2019

SDF had not withdrawn from any positions east of Euphrates despite the passage of 37 hours of the US-Turkish agreement to suspend the Turkish military operation for 120 hours according to SOHR. SOHR also reported that since the start of the operation, Turkish Armed Forces and allies had captured an area of 2,419 square kilometres (934 sq mi). Both sides claimed that the other side was violating the ceasefire. The SDF stated that Turkish forces prevented medical aid from reaching Ras al-Ain, a claim backed by SOHR. Unnamed US officials said the "ceasefire is not holding". In the afternoon the SDF said an aid convoy had been let through, after having been prevented from entering the town since Thursday.

20 October 2019

SDF withdraws from Ras al-Ayn

A Turkish soldier was killed by a mortar attack near Tal Abyad due to violations of YPG according to Turkish Defense Ministry, whilst the SDF stated that 16 fighters had been killed by Turkish forces. SDF fully withdrew from Ras al-Ayn alongside the aid convoy per SOHR. Both sides claimed that the other side made ceasefire violations.

Continued U.S. withdrawal

US forces withdrew from their airbase near Sarrin as well as their airbase near Tell Beydar and destroyed it per SOHR. US forces had completely withdrew from the countrysides of Aleppo and Raqqa per SDC as well. In the largest ground move to date, a United States convoy of almost 500 personnel moved eastward through northern Syria towards the border of Iraq. As they withdrew, locals threw rotten produce and shouted insults at them, demonstrating a sense of betrayal among the populace.

U.S. President Donald Trump favored leaving a contingent of 200–300 US troops in Deir ez-Zur countryside of eastern Syria where majority of the country's oil fields are located per NYT and WSJ. The SDF, however, stated that "The fields have stayed in our hands. We have an agreement with the regime to give them some of our positions along the Turkish border, but we have not negotiated with them on the oil fields yet. There will probably be a version of joint control and revenue sharing with the regime from these fields. I don’t know if Trump understands this."

21 October 2019

The SOHR reported continued ceasefire violations despite the withdrawal of the SDF from Ras al-Ayn. Per SOHR, Turkish drone strikes had targeted a vehicle carrying 4 members of the SDF near Ain Issa, resulting in the death of all fighters. The Abu Rasin area, east of Ras al-Ayn also experienced heavy clashes and shelling by Turkey as per SOHR.

On the aftermath of the SDF withdrawal from the Ras al-Ayn, there were widespread accounts of looting, theft, burning of houses and kidnappings by the pro-Turkish forces with documented examples of members of the Hamza Division per to the SOHR.

The SOHR reported a US withdrawal from northern Syria with a military convoy passing through Simalka border into Iraq at midnight.

Russian Defense Minister Sergei Shoigu has stated that Russia would need to deploy additional troops and equipment to Syria to patrol the border.

According to Syrian state news channel Al-Ekhbaria, Syrian President Assad has told Russian President Putin that his government rejects the occupation of Syria's lands under any pretext in a phone call today. In a reference to the SDF during his visit to the war zone near Al-Habeet in Idlib, the Syrian President Assad stated that "We said we are ready to support any group that takes up popular resistance against Erdogan and Turkey. This is not a political decision, we have not made a political decision, this is a constitutional duty and this is a national duty. If we don't do this, we don't deserve the homeland."

Russian–Turkish memorandum

On 22 October 2019, Russian President Vladimir Putin and Turkish President Recep Tayyip Erdoğan met in Sochi and reached an agreement about the situation in Syria. They subsequently released a 10-point memorandum detailing the provisions of the agreement.

In the agreement, the established status quo of the Operation Peace Spring area, covering Tell Abyad and Ras Al Ayn with a depth of 32 kilometers from the border, will be maintained. Starting from 12.00 noon on 23 October, Russian military police and Syrian border guards would enter the Syrian border territory outside the Operation Peace Spring area to facilitate the removal of the YPG in the area with a depth of 30 kilometers from the border, which would be finalized within 150 hours. Hereafter, joint Russian–Turkish patrols would start to the west and east of the Operation Peace Spring area to a depth of 10 kilometers from the border, excluding Qamishli city. The YPG would be removed from both Manbij and Tal Rifat.

President Trump announced that there was a 'permanent' ceasefire in the region and sanctions on Turkey would therefore be lifted, but he also added that the word 'permanent' is questionable for that part of the world. US lawmakers publicly criticized Trump's decision to lift the sanctions.

Dmitry Peskov, the Russian presidential press secretary, urged the Kurdish forces to withdraw from Syria's border namely because the Syrian border guards and Russian military police would have to step back otherwise, adding that the remaining Kurdish units would be 'steamrolled' by the Turkish military. Peskov further stated that the United States had both betrayed and abandoned the Kurds despite being their closest ally in recent years.

As Newsweek first reported, it's stated that the United States is considering and preparing to deploy tanks and troops to defend the oil in eastern Syria.

US Defense Secretary Mark Esper said the United States would send troops, including 'mechanized' forces, to defend the oil in eastern Syria to keep it from ISIL. It was unclear whether the Kurds would welcome the Americans again in the aftermath of the US withdrawal, as Syrian Kurdish leader Ilham Ahmed commented earlier on 24 October that "If the U.S. presence in the area is not going to benefit us when it comes to stability, security, and the genocide and ethnic cleansing, they won’t be welcomed."

In response, the SDF said that they appreciated the efforts to unify Syria's defense and repel the Turkish aggression but also stated: "Our position was clear from the beginning, wherein uniting the ranks should begin from a political settlement that recognizes and preserves the exclusivity of the SDF and its structure, and creates a sound mechanism for restructuring the Syrian military establishment as an overarching framework for unifying efforts."
