Vladimir Putin will meet with the presidents of Turkey and Iran Wednesday for a key summit aimed at re-booting the peace process in Syria, a day after the Russian leader hosted surprise talks with Bashar al-Assad.
Putin's meeting with Turkey's Recep Tayyip Erdogan and Iran's President Hassan Rouhani comes as Ankara, Moscow and Tehran cooperate with increasing intensity on ending the civil war in Syria that has claimed some 330,000 lives and made millions homeless.
