The death toll from the fire that raged through a tobacco packaging factory at Tongi has climbed to 31 with the recovery of two more bodies from the debris on early Monday.

The firefighters rescue team retrieved the bodies from the wreckage on the fourth floor of the six-storey building at about 6:45am, and sent those to Dhaka Medical College Hospital.

A blast at Tampaco Foils Ltd sparked off huge fire at about 6:00pm on Saturday and led to the collapse of the four-storey factory.
