U.S. Vice President Mike Pence said on Thursday he had reached a deal with Turkish President Recep Tayyip Erdogan for a cease-fire in northern Syria to end an eight-day-old Turkish offensive against Kurdish-led forces.

Speaking after crisis talks with Erdogan in Ankara, Pence said that under the deal all military operations would be paused to allow a pullback of Kurdish YPG militia over a 120-hour period. The Turkish military operation would end once that withdrawal was complete, Pence told a news conference.

"Today the United States and Turkey have agreed to a cease-fire in Syria," Pence told a news conference after more than four hours of talks at the presidential palace in Ankara.
