The Kurdish-led Syrian Democratic Forces (SDF) are fighting Syrian government forces near al-Aqtan prison on Raqqa's outskirts, where Islamic State prisoners are held. The SDF called this an “extremely dangerous development.” The clashes occurred less than 24 hours after Syria’s president Ahmad al-Sharaa announced a ceasefire with the SDF and plans to end their control over northeast Syria. The SDF warned, “The level of threat is escalating significantly, amid attempts by these factions to reach the prison and seize control of it.” They added such moves could cause “serious security repercussions,” risking a return of chaos and terrorism. The Syrian army reported through state news agency Sana that three servicemen died and others were wounded in two attacks. It blamed “some terrorist groups” for trying to disrupt the ceasefire but did not specify locations. This sudden conflict raises concerns about the SDF's ability to guard prisons and camps with tens of thousands of Islamic State detainees. In Raqqa city, Kurdish sources say locals emptied two prisons after government forces took control. Thousands of IS prisoners from about 70 countries remain in Kurdish areas to the northeast, detained since IS lost territory in 2019. Female detainees and families are mostly held in al-Hawl camp, housing around 26,000 people, and the smaller Roj camp where fugitive Shamima Begum is held. About 4,500 male detainees are at Panorama and Gweiran prisons. The new ceasefire deal calls for the Syrian government to take full legal and security control of IS prisoner camps and integrate the current administration and guards. The Kurdish-led forces, backed by the US, had managed these camps after IS's defeat but with US troops withdrawing, Syria is expected to assume responsibility. Many Kurds distrust the government, worried it could loosen security over IS networks. Among detainees are about 55 from the UK, including Begum, some stripped of citizenship. British human rights group Reprieve called the crisis “a reality check” for Britain’s refusal to bring back detainees, urging urgent repatriation and prosecution where appropriate. President Ahmad al-Sharaa, once linked to al-Qaida and a former jihadist leader, has struggled to secure full authority since toppling Bashar al-Assad in 2024. A previous agreement to merge SDF forces with Syria’s national army failed amid mutual accusations of breaking the ceasefire.
