Syrian state TV says an explosion rocked eastern Aleppo as some residents were returning to their homes after the government assumed full control of the city earlier this week.

It says the explosion on Saturday was caused by a device left inside a school by Syrian rebels, who withdrew from their last remaining enclave under a cease-fire deal after more than four years of fighting.

A correspondent for Lebanon's Hezbollah-run Al-Manar TV was reporting live from the area when the blast sounded in the background, sending a huge cloud of dust into the air. The correspondent later said that at least three people were killed.

The rebel pullout from Aleppo, which was completed on Thursday, marks President Bashar Assad's greatest victory since the conflict began in 2011.
