The official made the remarks despite Turkey’s pledge to clear the Kurdish People’s Protection Units (YPG) from Manbij, in northern Syria.

“U.S. forces are located in Manbij. We have made it very clear with the Turkish government that we will continue to operate there,” said Heather Nauert at a press conference in response to a question about the U.S.’ stance on Manbij.

Nauert also said talks with Ankara have not been concluded and Washington is willing to continue the conversations, referring to the three technical committees of Turkey and the U.S., formed to solve issues between the two countries.

Turkey launched “Operation Olive Branch” on Jan. 20 to clear YPG militants from Afrin. The Free Syrian Army took full control of the city on March 18.
