The explosion destroyed a multi-storey building, killing at least 7 people and injuring dozens of others.
Officials said that Bangladeshi authorities have launched an investigation into a deadly explosion in Dhaka that killed at least seven people.
Sunday’s explosion is believed to have been caused by cooking gas accumulated in a four-story building in the central area of Mogbazar, the capital of Bangladesh. The building houses shops, showrooms and private offices. Ten people were injured.
The explosion also damaged at least three city buses carrying passengers who were trapped in traffic jams in front of the building and other places around the building.
Samanto Larson, head of the Department of Burns and Plastic Surgery at Dhaka Medical College Hospital, said that 12 people with burns are said to be in critical condition.
Fire and Civil Defense official Debashish Bardhan said members of a four-person investigation team collected evidence on Monday.
He said that the expert team would report the cause of the explosion within 7 days, adding that investigators initially attributed the explosion to the cooking gas accumulated in the restaurant on the first floor.
Bangladesh Police Chief Benazir Ahmed said there is currently no evidence of vandalism. But he said that explosives experts will launch an investigation.
He said: “We will wait until the investigation report has final comments.”
Civil engineers from the Works Department also inspected the damaged building built more than 60 years ago to see if it is suitable for use.
In Bangladesh, deaths from gas leaks and explosions due to poor maintenance and lax application of laws are common.
In September, such an explosion occurred at the Narayan Ganj Mosque, about 25 kilometers (15.5 miles) south of Dhaka, killing at least 33 people.
