Turkish presidential sources who requested anonymity due to restrictions on speaking to media said Erdogan stressed Sunday that Turkey "will never allow a terror corridor in our south and in Syria’s north".
He also informed Markel about Turkey's Operation Euphrates Shield, launched Aug. 24 with the aim of improving security, supporting United States-led coalition forces, and eliminating the terror threat along Turkey’s border through Free Syrian Army fighters backed by Turkish armor, artillery, and jets.
Merkel reiterated Germany's support for Turkey's fight against all terrorist groups, especially Daesh.
The chancellor also underlined that Germany condemned the July 15 coup attempt -- which left 240 people martyred and 2,200 others injured -- and took the side of democracy.
Erdogan responded by expressing his gratitude for Merkel's phone calls in support of Turkey after the failed putsch blamed on the Fetullah Terrorist Organization (FETO) and military personnel linked to it.
The two leaders also agreed on further developing economic, political and cultural ties between Turkey and Germany.
The 11th G20 summit, attended by the leaders of the world’s 20 most industrialized countries, is being held in the coastal city of Hangzhou in Zhejiang province Sept. 4-5.
