U.S. troops have begun pulling out of positions in northern Syria, The Associated Press reported on Monday, citing U.S.-backed Kurdish forces.

Turkish President Recep Tayyip Erdoğan also reportedly said American troops have started to withdraw from the area.

The White House announced late Sunday that Turkey will soon be launching a military operation in the region and that U.S. troops will no longer be “in the immediate area” when it happens. ADVERTISEMENT

The Kurdish-led forces denounced the move as a “stab in the back," according to Reuters.

“We are hoping for the best but preparing for the worst,” Panos Moumtis, the U.N. regional humanitarian coordinator for the Syria crisis, told reporters in Geneva, the news service noted.

The U.S. had more than 1,000 troops deployed in northern Syria, working closely with the Kurdish-led forces.
