At least 25 people have died in a fire at a furniture factory north of the Egyptian capital Cairo, officials say.

A further 22 people suffered injuries from burns and smoke inhalation from the blaze in the city of Obour, media reports said.

The fire is thought to have started after a gas canister exploded while it was being transported in a lift.

The factory had not obtained a government safety certificate, Egyptian state media reported.

More than 20 fire trucks eventually brought the blaze under control.

Such accidents are relatively common in Egypt. A separate fire at a food market in Alexandria, Egypt's second-largest city, has injured at least 11 people.
