President Erdoğan to attend trilateral summit in Tehran

Turkish President Recep Tayyip Erdoğan is set to attend a trilateral summit that will be held in the Iranian capital Tehran on Sept. 7, according to presidential sources.

Erdoğan is expected to meet his Iranian and Russian counterparts during the summit, where they will discuss Syria.

Syria has been locked in a vicious civil war since early 2011 when the Assad regime cracked down on pro-democracy protests with unexpected ferocity.

The Kremlin said nearly two weeks ago that Russian President Vladimir Putin may take part in a meeting with Erdoğan and Iranian President Hassan Rouhani at the beginning of September. The three leaders met in April in Ankara, where they discussed developments in Syria.
