The US military has launched a mission to transfer up to 7,000 Islamic State (IS) group fighters from prisons in north-eastern Syria to Iraq, as Syrian government forces take control of areas long controlled by Kurdish-led forces. US Central Command said it had already moved 150 IS fighters from Hassakeh province to a secure location in Iraq. The move aimed to prevent a breakout that would pose a direct threat to the United States and regional security, it added. On Tuesday night, Syria's government announced a new ceasefire with the Kurdish-led Syrian Democratic Forces (SDF), after the militia alliance withdrew from al-Hol camp, which holds thousands of relatives of IS fighters. Separately on Wednesday, Syria's defence ministry said seven soldiers were killed in a drone attack by Kurdish forces in the Kurdish-dominated province of Hasakah.
