At least 11 people including four children were killed when a war-damaged apartment block collapsed in the city of Aleppo.

Axar.az reports citing foreign media.

A child was the only survivor from the collapse in the formerly rebel-held area of Salaheddin, which was bombed by Syria and Russia before being retaken.

Residents have been eking out a living in ruins across Syria, with little rebuilding taking place.

Syria's authorities have so far focused their efforts on basic infrastructure.

Several other buildings in Salaheddin near the five-storey block that caved in are on the brink of collapse, AFP reported.
