The explosion passed through 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 fatal 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, which houses shops, showrooms and private offices, causing several damages. 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 Larsson, 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 blamed the explosion on the cooking gas accumulated in the restaurant on the first floor.
Benazir Ahmed, the Chief of Police of Bangladesh, said that 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 a final comment.”
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 Narayanganj Mosque, about 25 kilometers (15.5 miles) south of Dhaka, killing at least 33 people.
