A woman who sustained severe burn injuries in a gas explosion in Halishahar area of Chattogram died on Monday afternoon while being taken to Dhaka for advanced treatment.

The deceased was identified as Nurzahan Akter Rani, 40. She died around 4:30pm on the way to the capital, police and hospital sources said, adding that she had suffered 100 percent burns.
