BEIRUT (AP) — A building collapsed in a neighbourhood in Syria’s northern city of Aleppo early Sunday, killing at least 16 people, including one child, and injuring four others, state media reported.

The five-storey building housing about 30 people is in the Sheikh Maksoud neighbourhood under the control of the US-backed Kurdish-led Syrian Democratic Forces. It collapsed overnight, according to the report, after water leakages weakened the structure’s foundation.

Dozens of firefighters, first responders and residents covered in debris and dust were searching through the rubble for the remaining residents with drills and a bulldozer.

Some relatives of the tenants waited anxiously nearby, while others mourned at the entrance of a nearby hospital as the bodies arrived in ambulances and on the backs of trucks.

Hawar News, the news agency for the semiautonomous Kurdish areas in Syria, initially reported that seven people were killed and three were injured, two of them critically.

Many buildings in Aleppo were destroyed or damaged during Syria’s 11-year conflict, which has killed hundreds of thousands and displaced half the country’s pre-war population of 23 million.

Although the Syrian government under President Bashar Assad has retaken Aleppo from armed opposition groups, Sheikh Maksoud is among some neighbourhoods under the control of Kurdish forces.

Aleppo is Syria’s largest city and was once its commercial center.
