Arson Blamed for Fire at Bangladesh Garment Factory - Central Coast News KION/KCBA

DHAKA, Bangladesh-- Bangladesh said on Tuesday a fire that killed 111 textile workers was sabotage as protesters took to the streets for a second day and garment factories across the world's second biggest clothes exporter stopped work to mourn.

The country's worst-ever industrial blaze broke out on Saturday and consumed a multi-story building of a Tazreen Fashions factory. More than 150 workers were injured.

The fire has put a spotlight on global retailers that source clothes from Bangladesh, where the cost of labor is low - as little as $37 a month for some workers - and rights groups have called on big-brand firms to sign up to a fire safety program.
