Two out of the nine members of a family, all of whom had suffered serious burns in a house fire in Narayanganj's Fatullah on Wednesday, died at the Burn Unit of Dhaka Medical College Hospital yesterday.

The dead are Haridasi, 55, and her daughter Sumitra Das, 27.

Quoting the duty doctors, Bacchu Miah, sub-inspector of DMCH police outpost, said Haridasi had died in the early morning while Sumitra breathed her last around 10:00am.

The bodies are kept at the DMCH morgue, he added.

The condition of the seven other victims -- Shib Nath Das, 35, Archana Rani Das, 28, Arpit Das, 10, Anamika Das, 15, Narayan Chandra Das, 40, Pramit, 14 and Shaon, 10 -- is also critical, the SI added.

The fire took place inside a second floor-flat of a four-storey building in Kotowaler Bagh area around 6:30am.

Abdullah Al-Arefin, assistant deputy director of Narayanganj Fire Service and Civil Defence, said the fire might have had originated from a burning mosquito repellent coil while all the nine members were sleeping in the room with all the doors and windows closed.
