Violence erupts as workers in Dubai down tools over pay and conditions.

Work on the world's tallest building, the Burj Dubai tower, was stopped yesterday after 2,500 workers rioted over pay and conditions.

The workers have caused damage worth an estimated £500,000 since the trouble broke out on Tuesday night. It is understood that trouble started when buses due to transport workers to a residential camp at the end of a shift were delayed.

The workers are then reported to have chased and assaulted security officers, broken into offices and destroyed about 25 cars and construction machines.

Workers on the site are believed to want improved pay. Skilled carpenters working on the site earn £4.34 a day, while labourers are on £2.84 a day.

Construction staff building a new terminal at Dubai International Airport also stopped work in sympathy yesterday.
