The death toll from the gas line blast now stands at three.

Earlier on Friday, two women were killed and more than 15 others injured after a five-storey building in Narayanganj’s Fatullah area partially collapsed following an explosion in the gas line.

Narayanganj Fire Service assistant deputy director Abdullah Al Arefin said a gas leak led to the explosion at the building owned by Moktar Mia in Lalkhan Mor around 6am.

The explosion triggered the collapse of the walls of some flats in the building, which in turn, created a ripple effect and led to the wall collapse in three adjoining houses, leaving Maya Rani dead on the spot and eight injured in the immediate neighboring building.

The injured were sent to Dhaka Medical College and Hospital (DMCH) in a critical condition.

Also injured were Mangali Rani who was taking a stroll with her daughter Purnima. Both were taken to Victoria Hospital in the city, where the mother succumbed to her injuries, the fire officer said.
