At least 112 people were killed in a fire that raced through a multi-storey garment factory just outside of Bangladesh's capital, an official said Sunday.

The blaze broke out at the seven-storey factory operated by Tazreen Fashions late Saturday. By Sunday morning, firefighters had recovered 100 bodies, fire department Operations Director Maj. Mohammad Mahbub told The Associated Press.

He said another 12 people who had suffered injuries after jumping from the building to escape the fire later died at hospitals.

The death toll could rise as the search for victims continues, he said.

Mahbub said army soldiers and border guards had been deployed to help police keep the situation under control as thousands of anxious relatives of the factory workers gathered at the scene.

He would not say how many people were still missing.

Bangladesh has some 4,000 garment factories, many without proper safety measures. The country annually earns about $20 billion from exports of garment products, mainly to the United States and Europe.
