At least 4,000 rebels and their families will be evacuated from the last opposition-held districts of Syria's Aleppo, state television reported on Thursday. 

"All the procedures for their evacuation are ready," the television said in a breaking news alert. 

A new agreement has been reached for the evacuation of rebel fighters from the last pocket of territory they control after the collapse of a previous deal amid heavy fighting on Wednesday, a senior Syrian military source told AFP.
