The Kurdish YPG militia will pull forces and heavy weapons from a strip along Syria's border with Turkey under U.S.-Turkish deals, an official in the YPG-led alliance said on Tuesday.

The YPG withdrew from the Tal Abyad and Ras al-Ain border positions in recent days, proving it is serious about ongoing talks, the Kurdish-led authority in north and east Syria said.

The withdrawal marks a sign of progress in talks between Washington and Ankara seeking to resolve deep differences over the presence along the border of Kurdish fighters — U.S. allies that Turkey sees as enemies.
