At least 250 people have died after an eight-storey building collapsed in Dhaka in Bangladesh and more than a thousand are still missing.

Locals continue to hunt for survivors trapped in the wreckage of the Rana Plaza building in the commercial suburb of Savar, 20 miles outside the capital Dhaka.

The disaster has refocused attention of Western brands that use Bangladesh as a source of low cost labour to produce cheap goods.

British retailer Primark and the UK based company Premier Clothing, which specialises in selling uniforms for the workplace, were among firms supplied by factories in the building.
