The leaders of Turkey, Iran and Russia say they're committed to finding a lasting ceasefire in Syria and to protecting civilians in de-escalation zones.
Russian President Vladmir Putin, Iranian President Hassan Rouhani, and Turkey's Recep Tayyip Erdogan met in Ankara to discuss Syria's future.
It's the second such summit after another in Sochi, Russia, in November.
The three countries are key players in Syria with Russia and Iran backing Syrian President Bashar al-Assad and Turkey supporting the opposition.
They've jointly sponsored several rounds of earlier peace talks and brokered an agreement to create four de-escalation zones.
