Baghouz: Dozens of Islamic State group jihadists emerged from tunnels to surrender to US-backed forces in eastern Syria on Sunday, a day after their "caliphate" was declared defeated.

Syria's Kurds warned that despite the demise of the proto-state, the thousands of foreign jihadists they have detained are a time-bomb the world urgently needs to defuse. An AFP reporter saw dozens of people — mostly men — file out of the battered jihadist encampment in the remote village of Baghouz near the Iraqi border to board pickup trucks.
