7 dead, dozens injured after explosion causes building collapse in Bangladesh

A gas line explosion caused the collapse of a building in Bangladesh's seaport city of Chattogram on Sunday morning, leaving at least seven people dead and over 25 injured, a police official said.

The official, who did not want to be named, said at least 32 people were injured after an explosion caused the front part of an old house's ground floor to collapse at about 9:30 am (local time).

All the injured were rushed to nearby hospitals, said the official, adding that about "seven injured people succumbed to their injuries at the hospitals."

Officials believed that a gas leak-triggered explosion might have caused the incident.

Gas accidents are relatively common in Bangladesh.

In October, at least seven people including six children were killed when a gas cylinder exploded in the Bangladeshi capital of Dhaka.

In February, at least 81 people were killed as a devastating fire, triggered by a gas cylinder explosion, tore through a number of buildings in the old part of Dhaka.
