At least six people were killed and several injured on Saturday when a fire broke out following an explosion at an oxygen plant in southeastern Bangladesh, officials said.
The death count could rise as a rescue operation was ongoing at the plant at Sitakunda, 40 km (25 miles) from the southeastern port city of Chittagong, they added.
It was not immediately clear what caused the explosion, a fire service official said.
"Six bodies were recovered from the site," local government official Shahadat Hossain told Reuters, adding a rescue operation was continuing.
A huge bang was heard which shook an area with a radius of up to two kilometers, police official Nayhanul Bari said, quoting witnesses.
