At least 17 worshippers killed during Friday night prayers when a blast sent flames raging through the mosque

The explosion, which fire service officials suspect was caused by leakage from the pipeline in the mosque in Narayanganj district on Friday night, also injured dozens with critical burns as worshippers were about to end their prayers.

Dozens were rushed to Dhaka’s state-run specialised burn and plastic-surgery hospital, most of them with severe burns.

Samanta Lal Sen, coordinator of the burn unit, on Saturday said the dead included a seven-year-old boy. He said doctors were treating at least 37 people with burns on up to 90 percent of their bodies.

“I saw smoke was belching out of the mosque after the sudden explosion with a big bang and people were screaming. Some were rolling on the street as they tried to put out the flames on their bodies,” Mohammad Ratan, a local resident, said.

Fire officials said gas that accumulated from a leak in a pipeline running underneath the mosque likely triggered the explosion.

Authorities have launched an investigation into the blast.

In Bangladesh, safety regulations are often flouted in construction. Hundreds are killed each year in fires in the nation of 168 million people.

Faulty installation of gas lines are often reported by Bangladeshi media, while unplanned road-digging work often leads to disasters in the country which is seeking rapid industrial expansion and economic development.

In February last year, an inferno in Dhaka’s old quarters killed 78 people. One month later, 25 people were killed when a blaze engulfed an office building in the city.
