At least 15 people have been killed and more than 70 people injured in a huge fire that broke out at a packaging factory in  Bangladesh. 
Police said about 100 people were working in the four-storey building in the town of Tongi, just north of the capital Dhaka, at the time. 
The blast was caused by a boiler explosion, and flames quickly spread throughout the building, officials say. 
The fire is not yet under control, the emergency services say. 
"The death toll has risen to 15 and at least 70 people have been injured," the BBC quoted Parvez Mia, a doctor at the town's hospital, as saying. 
"Most of them had burn injuries. We sent the critically injured victims to the hospitals in Dhaka," he added.
