Police in Bangladesh say at least 50 people have been injured in clashes between police and workers at a textile factory.
Security officials say hundreds of workers from the Nippon Garments factory outside the capital Dhaka took to the streets Saturday to demand unpaid wages.
Police fired rubber bullets to disperse the protesters, who were hurling bricks.
The workers also blocked a key highway, and set fire to vehicles.
Garment manufacturing is the largest sector of Bangladesh's economy, counting for more than three-quarters of the nation's exports.
The industry was hit hard by the global economic downturn.
