Eight people dead and more than 30 rescued after Lagos school collapse

Eight people have died after a school building collapsed in Nigeria, emergency officials said.

A total of 37 people have been rescued alive as rescue efforts continue under floodlights and into the night at the scene in Lagos.

Witnesses said up to 100 children could have been in the primary school when the three-storey building collapsed on Wednesday.

Footage shows rescuers carrying several dust-covered, stunned-looking children from the debris, to cheers from hundreds of people who had rushed to the scene.

Sani Datti, a spokesman with Nigeria's National Emergency Management Agency, said: "For now, we don't have any word on casualties as we are still busy with rescue work."

It is not immediately clear what caused the structure to collapse.

Hundreds of people stood nearby the scene waiting for news. A number of shirtless men - hacksaws and mallets in hand - were seen to jump in to offer help to the rescue workers.
