"If Russia does not end its airstrikes on Western-backed Syrian opposition forces, a ceasefire reached by major powers will not hold and humanitarian access will not be effectively secured," Turkish Foreign Minister Mevlüt Çavuşoğlu said on Friday.
Çavuşoğlu was speaking after a meeting in Munich, Germany at which the United States, Russia and a more than a dozen other nations agreed to cease hostilities to pave a way for a political transition in Turkey's war-ravaged neighbor.
Turkey and its partners do not object to Russia targeting groups such as Daesh and Nusra Front in Syria, but Moscow needs to do so in coordination with the US-led coalition, Çavusoğlu told Turkey's state broadcaster in comments broadcast live from Munich.
Çavuşoğlu also said Friday on his Twitter account that an agreement between major powers to cease hostilities in Syria to provide humanitarian aid was an important step toward resolving the crisis.
More than 250,000 people in Syria have been killed and more than 10 million displaced, according to United Nations' figures.
