Turkish President Recep Tayyip Erdogan arrived in Tehran on Wednesday to discuss the latest developments in the region.
Fearing Kurdish separatism within their own borders, Iran and Turkey have threatened to join Baghdad in imposing economic sanctions on Iraqi Kurdistan and launched joint military exercises with Iraqi troops at their borders with the region.
Erdogan will meet Iran's top authority Supreme Leader Ayatollah Ali Khamenei as well as President Hassan Rouhani during his one-day trip to Tehran.
The Kurds are the region's fourth largest ethnic group, spread across Iran, Turkey, Syria and Iraq, all of which oppose any moves towards sovereignty.
