Two security guards of a multi-storey residential building in Narayanganj city sustained burn injuries in a gas explosion on Sunday night.
The victims -- Ujjal and Manik -- are undergoing treatment at Sheikh Hasina National Institute of Burn and Plastic Surgery in Dhaka.
Narayanganj Fire Service and Civil Defence Deputy Director Abdullah Al Arefin said the eight-storey building named GM Garden on President Road in Chashara, has a large room used for events constructed at a portion on its rooftop.
Gas was being leaked from the stove at its kitchen for several days and it was repaired on Sunday night.
