Turkey has agreed to a ceasefire in northern Syria to let Kurdish-led forces withdraw, US Vice President Mike Pence has announced.
All military operations will be paused for 120 hours, and the US will help facilitate an "orderly withdrawal" of Kurdish-led troops from what Turkey has termed a "safe zone" on the border.
Turkey launched its assault last week.
It aimed to push Kurdish fighters from the border and create this "safe zone" to resettle Syrian refugees.
Critics fear this could lead to ethnic cleansing of the Kurdish population in the region.
The cross-border offensive came after US President Donald Trump pulled US forces out of the area.
His decision has prompted a raft of criticism at home and abroad, with some accusing him of giving Turkish President Recep Tayyip Erdogan a "green light" for the operation.
