10:50 a.m.

Syrian activists say shelling has resumed in the remaining rebel part of eastern the city of Aleppo, despite a cease-fire deal to allow for the evacuations of the opposition fighters and tens of thousands of civilians.

Aleppo media activist Mahmoud Raslan says he was reporting for a Turkish agency when a rocket crashed beside him at around 10:15 a.m. on Wednesday. He shared an audio recording of the explosion with the Associated Press.

The Britain-based Syrian Observatory for Human Rights says an explosion was heard in the rebel-held Saif al-Dawleh district around the same time.

Pro-government forces have trapped thousands of civilians and gunmen in eastern Aleppo under a crushing bombardment over the past weeks as they pushed to clear the northern city of the opposition.

The implementation of the deal struck on Tuesday to evacuate civilians and rebels from the enclave, signaling a surrender by the opposition, was delayed on Wednesday morning.

8:50 a.m.

The Syrian rebel pullout from their last holdout in the city of Aleppo has been delayed.

The withdrawal was supposed to start early in the morning on Wednesday after the rebels the previous day reached a cease-fire deal to evacuate from eastern Aleppo in what is effectively a surrender — and a defining moment in Syria's civil war.

The pan-Arab al-Mayadeen TV broadcast footage of Syrian government buses idling at an agreed-on evacuation point. It's unclear what has caused the delay.

The TV says it expects at least another couple of hours of delay. It says the buses are prepared to move 5,000 fighters and their families to Atareb, an opposition-held town in the northwestern Aleppo countryside.

The Syrian government or the opposition haven't made any announcements about the delay.
