The deadline for the withdrawal of Kurdish fighters from areas in northeastern Syria expires at 1900 GMT Tuesday, a Turkish military source said, as part of a 120-hour suspension agreed between Ankara and Washington.
"It started at 10pm Thursday... so it finishes at 10pm Tuesday," the source said.
Following the withdrawal, Turkey wants to set up a 120-kilometre (75-mile) "safe zone" between Tal Abyad and Ras al-Ain, they added, saying this will then be extended to 444 kilometres.
