The Kurdish-led Syrian Democratic Forces (SDF) says it has withdrawn from a camp holding thousands of people with alleged links to the jihadist group Islamic State (IS), as clashes with the Syrian government continue despite a ceasefire agreement.

The SDF said its forces were "compelled to withdraw" from al-Hol camp and redeploy to other cities in northern Syria "due to the international indifference toward the issue of [IS]".

The Syrian interior ministry condemned the move, saying it took place without any co-ordination with the government or US-led coalition against IS.

It came after suspected IS fighters escaped nearby Shaddadi prison during clashes between government forces and the SDF.

The interior ministry said 120 detainees broke out of the SDF-run Shaddadi prison on Monday but that soldiers and police had arrested 81 of the fugitives.
