U.S. President Donald Trump told his Turkish counterpart Recep Tayyip Erdogan in clear terms that it was "wrong" to supply weapons to PKK/YPG during their recent phone conversation, the Turkish prime minister has confirmed.

Axar.az reports quoting Anadolu Agency.

Binali Yildirim's comments came during an interview with BBC World.

"Mr. Trump understood what is important for Turkey," Yildirim said, in reference to Trump's pledge to Erdogan in a Friday phone call on ending the supply of arms to the terrorist PKK/PYD and PKK/YPG in Syria.

"They [U.S.] said this [cooperation with YPG or PYD] is not a choice. This is a necessity… Ok. We understand, although we do not accept. It is a temporary relation. Now, it is time to finish. Because ISIS is already defeated," the premier said. "So, President Trump said it is wrong to provide weapons. This is clearly mentioned."

Stating that Turkish policy on fighting against ISIS had been quite "clear" since the beginning, Yildirim said it was important to "choose the right partner" to fight ISIS.

"You are not able to fight a terror organization using another terror organization," he added.
