A fire in a garment factory in the outskirts of the capital of Bangladesh has killed more than 100 people, according to the fire brigade.
The blaze at the nine-story Tazreen Fashion factory in the Ashuila industrial belt of Dhaka started on the ground floor late on Saturday and spread, trapping hundreds of workers.
Witnesses said the workers, mostly women, ran for safety as the fire engulfed the plant, but were unable to get through narrow exits.
