GENEVA (Reuters) - Turkish President Tayyip Erdogan met Iranian Supreme Leader Ayatollah Ali Khamenei in Tehran on Friday after a trilateral summit with Russia about Syria, Khamenei’s official website reported.

The summit focused on a looming military operation in the Syrian province of Idlib, the last major stronghold of active opposition to the rule of President Bashar al-Assad, who has received military support from Russia and Iran.

Erdogan pushed for a ceasefire during the summit but Russian President Vladimir Putin said a truce would be pointless as it would not involve Islamist groups it deems terrorists.
