ANKARA Turkish President Tayyip Erdogan discussed the situation in Syria's Aleppo with his Russian counterpart Vladimir Putin by phone for the third time in a week on Wednesday and agreed on the need for a ceasefire, sources in Erdogan's office said.
The sources said the two leaders agreed on intensifying efforts toward a cessation of hostilities and on the need for the provision of aid to the city, the sources said.
Russia is a main backer of Syrian President Bashar al-Assad, while Turkey supports the rebels fighting to oust him, but the two have been trying to find common ground on Syria since a rapprochement in August.
Syrian rebels on Wednesday vowed to fight on in east Aleppo in the face of sudden government advances that have cut the city's opposition sector by a third and brought the insurgents to the brink of a catastrophic defeat.
