Turkish President Recep Tayyip Erdoğan met with Palestinian President Mahmoud Abbas and Hamas leader Ismail Haniyeh at his office in Ankara on Wednesday, Agence France-Presse reported, citing the official Anadolu news agency.
The meeting was held behind closed doors, it said.
Israeli Prime Minister Benjamin Netanyahu was also due to visit Turkey this week, but his visit was later postponed after he had surgery last weekend and as Israel is roiled by protests over contentious judicial reform.
After several years of tension, relations between Turkey and Israel have improved over the past year, with several high-level visits, including that of Israeli President Isaac Herzog.
Erdoğan on Tuesday promised to continue supporting the Palestinian cause and voiced concerns over the flareup of violence in the West Bank in recent months, after meeting with Abbas.
Israeli troops killed a Palestinian in the occupied West Bank on Wednesday, the Palestinian health ministry said, as the army confirmed it was conducting “counterterrorism activity” in a Nablus refugee camp.
