Thousands of angry textile workers have demonstrated in the outskirts of Dhaka after a fire swept through a garment workshop at the weekend, killing more than 100 people in Bangladesh’s worst-ever factory blaze.

The fire has put a spotlight on global retailers that source clothes from Bangladesh, where the cost of labour is as little as $37 a month. Rights groups have called on big- brand firms to sign up to a fire safety programme.

Workers from Tazreen Fashions and residents blocked roads yesterday and forced the closure of other factories, demanding that those responsible for the disaster be punished.
