Turkey's presidential spokesman, US national security advisor discuss bilateral relations, developments in Syria on phone.

Axar.az reports citing AA that Turkey's Presidential Spokesman Ibrahim Kalin and U.S. National Security Advisor Robert O’Brien spoke about bilateral relations and recent developments in Syria on the phone on Monday.

According to a statement from the presidency, the officials stressed that the two NATO allies have to work together against all terrorist groups, including ISIS and the YPG/PKK.

Kalin and O’Brien also spoke about preparations for President Recep Tayyip Erdogan’s visit to President Donald Trump in Washington set for Nov. 13.

Their talk took place days after U.S. forces killed ISIS leader Abu Bakr al-Baghdadi. Announcing the terrorist’s death early Sunday, U.S. President Donald Trump thanked Turkey for its cooperation with the raid, calling it "terrific," adding that U.S. forces "flew over" some Turkish territory during the mission.

In response to these attacks, Turkey launched anti-terror operations at home and abroad, neutralizing 3,500 ISIS terrorists and arresting 5,500.
