The Turkish president and British prime minister in a phone call on Friday discussed a range of issues including the Azerbaijan-Armenia tension and the Eastern Mediterranean, an official statement said.

“Armenia should withdraw from the territories it occupied in and around Upper Karabakh, or Nagorno-Karabakh for peace and stability in the region,” Recep Tayyip Erdogan said, according to Turkey’s Communications Directorate.

Border clashes broke out early Sunday when Armenian forces targeted Azerbaijani civilian settlements and military positions in the occupied region.
