At least 25,000 textile workers took to the streets in Dhaka at the weekend to demand back-pay and bonuses according to local media reports.

At least 50 people, including four policemen, were injured in the clashes at the Tejgaon Industrial Area, the private UNB news agency said.

The country's military-backed government has banned all demonstrations in the textile sector, after a series of protests over low wages and poor working conditions in the past two years.

Factory owners and trade union leaders agreed a new monthly minimum wage for garment workers of 1,662 takas (US$25.4) in October 2006, but the unions say just 20% of factories have implemented the pay rise.
