Turkey has justifiable security interests in northeastern Syria, UN Secretary General Antonio Guterres said Friday amid calls for a buffer zone the area.
Guterres said any solution must take into account Syria's territorial integrity, the "legitimate security concerns" of Turkey, and recognition of Syria's diversity.
"These are the three criteria that we have in analyzing any proposal that might eventually exist," Guterres said.
In a Twitter post on Monday, U.S. President Donald Trump proposed the establishment of a 20-mile (32-kilometer) wide safe zone in Syria's eastern Euphrates region. Later, Turkish President Recep Tayyip Erdogan held a phone talk with his U.S. counterpart and evaluated the details of the safe zone.
