Five young people have died in a fire that broke out in a storage space in a residential block of flats in north-east Spain.

Residents raised the alarm about the fire in a five-storey building in the small town of Manlleu, about 80km (50 miles) north of Barcelona, shortly after 21:00 local time (20:00 GMT) on Monday, Catalonia’s fire brigade said. Four other people were slightly hurt in the blaze.

The identities of those who died is not yet known but reports said they include children and none of them lived in the building.

It is not clear why they could not escape the storage room, which is on the upper floor, according to firefighters. An investigation is under way into the fire’s cause.
