Intense Syrian bombing of besieged Aleppo, troops advance

Syrian warplanes, artillery and mortar rounds have pounded areas in the eastern rebel-held Aleppo enclave, killing at least three, according to opposition activists.

The Britain-based Syrian Observatory for Human Rights said the bombings in the central al-Shaar neighborhood killed three. The Syrian Civil Defense put the death toll at six.

The bombings Saturday came hours after government troops made new advances on the rebel-held parts of Aleppo city. State media reported that government and allied troops have moved in on new neighborhoods, pushing one kilometer (0.6 mile) deeper into the enclave from the far east. The new advances tighten the government's grip on the besieged enclave and reduce the territory the rebels hold by more than half.

The new advances also secure the airport road east of Aleppo.
