Turkey's President Erdoğan holds phone call with Donald Trump

Turkish President Recep Tayyip Erdoğan and his U.S. counterpart Donald Trump discussed bilateral and regional issues in a telephone conversation on Thursday, according to the Turkish presidency.

Presidential Spokesman İbrahim Kalın told Anadolu Agency: "Our president held a telephone conversation with U.S. President Trump.

"Bilateral and regional issues were discussed during the conversation."

Speaking in an interview with the official Anadolu Agency, Foreign Minister Mevlüt Çavuşoğlu previously said Thursday that the two leaders will hold a phone call later in the day.

Çavuşoğlu also said that, if the U.S. and Turkey cannot agree on a path forward in Manbij, Turkey would move to clear PKK-backed People's Protection Units (YPG) from the northern Syrian city.

"If this plan is not realized, the only option left will be clearing away terrorists. This is not just valid for Syria, but also for Iraq," he said.

Çavuşoğlu was due to meet former Secretary of State Rex Tillerson on March 19 to discuss a roadmap for Syria's Manbij, including the withdrawal of YPG and the return of weapons handed to the terrorists by the U.S. Despite the delay caused by Trump's sacking of Tillerson, Turkish officials said they expect the U.S. to act in accordance with the common understanding reached by both sides.

The northern Syrian city of Manbij has been one of the most hotly debated points of discussion between Turkey and the U.S.

Ankara had requested the U.S., beginning with former President Barack Obama, to withdraw the YPG from areas east of the Euphrates and Manbij, and to stop supporting the group militarily. The U.S. had promised to meet Turkey's demands, but has not so far, which has strained relations between the two countries.

On March 20, Turkey launched Operation Olive Branch to clear YPG/PKK and Daesh terrorists from northern Syria, capturing the town of Afrin on March 18.
