A fire broke out at a garment factory in Bangladesh and a nearby chemical warehouse on Tuesday, killing at least nine people and wounding one, with the death toll expected to rise, officials said.

“Nine bodies have been recovered from the second and third floors of the garment factory,” fire service director Tajul Islam Chowdhury said, adding that recovery operations continued.

He said the cause of the blaze wasn’t immediately known.

The fire started on the third floor of the seven-storey factory in Dhaka’s Mirpur area before spreading to the chemical warehouse that stored bleaching powder, plastic and hydrogen peroxide, another official of the Fire Service and Civil Defence department said, citing witnesses.

Chowdhury said the factory owners had not yet been identified.

“The police and the army are looking for them.”
