DHAKA: Mass funerals were held Friday for victims of a devastating fire in Dhaka -- fuelled by illegally stored chemicals -- that killed nearly 70 people, as investigators revealed that an even bigger disaster was narrowly avoided.
Hundreds of chemical drums were found in the basement of one of five blocks engulfed by the inferno in the Bangladesh capital's historic Chawkbazar district.
"A huge bomb" would have gone off had the fire spread to the basement, according to Mehedi Hasan Ansary, a professor at an elite engineering university who is a member of an official probe committee.
"The impact would have been devastating," he told AFP.
City authorities said 46 bodies from a disaster that saw victims burned alive by fireballs in the street have been identified and handed over to families for burial.
Many were from Noakhali district in southwest Bangladesh, where funerals were quickly organised in line with Muslim tradition.
Special prayers were also said at Friday prayers in mosques across the country.
Police forensic experts were brought in to carry out DNA tests on at least 21 other bodies burned beyond recognition.
The discovery of the huge consignment of drums raised new fears about the extent of the deadly danger in storerooms across the labyrinthine Chawkbazar district.
"We were just lucky," said national fire chief Ali Ahmed.
"The whole neighbourhood would have been engulfed if the fire had reached the chemicals in the basement.
It would have been like a bomb and the building would have collapsed," Ahmed told AFP.
The fire is believed to have been started late Wednesday by a gas cylinder explosion which quickly spread to at least five buildings.
Victims were burned alive by exploding canisters that sent fireballs into the streets, smothering people in flames as they walked, rode in rickshaws or ate in local restaurants.
Dozens were injured, including nine listed in critical condition.
The disaster was a repeat of a June 2010 fire in the nearby neighbourhood of Nimtoli in which 123 people were killed.
Again a blaze ripped through residential buildings that doubled as chemical warehouses.
