Bangladesh officials say a fire at a garment factory has killed at least 100 people. Rescue workers found the bodies early Sunday.

Authorities say the blaze broke out Saturday night in the Tazreen Fashions factory outside Dhaka, the capital of Bangladesh.

Various reports say many workers were trapped on upper floors of the multi-story building. Some workers jumped to their deaths before rescue workers arrived on the scene.

The cause of the fire was not immediately clear.

Bangladesh has about 4,000 garment factories that make clothes for international brands.

Meanwhile, authorities say the girders of an overpass that was under construction in southeastern Bangladesh have collapsed, killing at least 11 people.

Officials say the girders crashed Saturday evening in the port city of Chittagong.

Police say dozens of people are missing.
