Presidential sources said that in the call both leaders agreed that a full cessation of hostilities should be implemented as soon as possible after Assad regime forces and Iran-backed Shiite militias attacked Aleppo despite the partial truce deal reached yesterday.
The two also underlined that the international community should work together to safely evacuate civilians and the opposition from eastern Aleppo.
Underlining the importance of 'humanitarian corridors' for evacuations, Erdoğan told Putin that Turkey was ready to take all possible measures to provide humanitarian aid and temporary shelter to those fleeing Aleppo.
Deputy PM Şimşek had announced Tuesday that a tent city to accommodate up to 80,000 Syrian refugees fleeing eastern Aleppo would be set up soon.
An evacuation of besieged opposition districts was announced late on Tuesday but did not go ahead as planned early on Wednesday after Iran, one of Bashar Assad's main backers, imposed new conditions, saying it wanted opposition fighters to allow the simultaneous evacuation of two villages.
A ceasefire that had coincided with news of the evacuation plan broke down and fighting raged again in Aleppo on Wednesday.
