Turkey is hoping a ceasefire in Syria will be implemented before the Qurban Bayram (Feast of the Sacrifice), also known as Eid al-Adha, Foreign Minister Mevlüt Çavuşoğlu said on Friday.
Speaking to reporters after holding a phone call with Russian Foreign Minister Sergei Lavrov, Çavuşoğlu said: "The process is being followed closely by Turkish officials, however, it is not easy to hold negotiations without a ceasefire."
He signaled that some "good news" on an agreement to halt fire could possibly be received before midnight.
The foreign minister said that giving a certain date for a peace deal is hard as the talks on how to conduct a transition process as well as the fight against terrorist groups is still in progress.
"The terrorist factions must be cleansed from Syria and Iraq in order to meet the necessary conditions for a peace deal, an agreement between the parties is not enough by itself," Çavuşoğlu said.
Turkey and Russia remain on the two opposite ends of the Syrian conflict, with Moscow backing Assad and Ankara supporting the opposition fighters.
President Recep Tayyip Erdoğan had met separately with Putin and the U.S. President Barack Obama on the sidelines of the recent G-20 meeting in China, telling them both that it was essential to agree on a truce for Aleppo.
Russia and the U.S. were believed to have been close to an agreement at the G20 but Washington then admitted that no deal could be announced for the moment.
