UPDATE 1-Fire kills at least 10 in Bangladesh capital, official says

A huge fire that broke out in a building in an old part of Bangladesh's capital, Dhaka, killed at least 10 people, a fire service official said on Thursday, and the death toll could climb further.

The blaze broke out on Wednesday and spread to other nearby buildings. Fire fighters fought for more than five hours to bring it under control, although it was still burning early on Thursday. Fire Service and Civil Defence Director General Ali Ahmed Khan told reporters at least 10 people were killed.

It was not immediately clear what caused the fire at the building in the centuries-old Chawkbazar area of Dhaka. Bangladesh media reported earlier that at least three people had been killed and several others taken to hospital.

Building safety regulations are rarely followed in impoverished Bangladesh, where accidents kill hundreds every year. The Rana Plaza factory collapse in 2013 killed more than 1,100 garment workers. (Reporting by Ruma Paul Editing by Hugh Lawson and Paul Tait)
