At least four workers have been killed after a gas cylinder exploded in a ship-breaking yard in southern Bangladesh, police said.
The explosion occurred while workers were removing parts from an old ship in the Kadam Rasul area of Sitakunda, 200 kilometres southeast of the capital Dhaka.
Six people were injured, four of whom later died in hospital, police officer Iftekha Hasan said.
“The workers might have died of inhaling toxic gas,” the officer said.
Bangladesh is the third largest country in terms of dismantling obsolete ships.
Safety measures in the yards are still inadequate.
At least 20 people were killed in 2013 in Bangladeshi ship-breaking yards, which are mostly located in Chittagong district, according to a human rights group.
