Footage of fire at Bangladesh plastics factory

At least 13 people have died and dozens have been injured in a fire at a plastics factory in Bangladesh's capital Dhaka, officials say.

The cause of the blaze in the multi-storey Nasim Plastic building is still unclear, but it may have triggered by a faulty gas cylinder or boiler.

Factory fires are common in Bangladesh, where safety conditions are often poor.

Footage showed fire-fighters tackling the blaze.
