At least four construction workers reported dead after a four-storey building collapses in Nairobi.

At least four people have died after a four-storey building under construction collapsed in the Kenyan capital Nairobi.

Rescuers are currently digging through the rubble in a bid to rescue trapped survivors.

A doctor at Kenyatta General Hospital said 67 people had been admitted with chest, leg and abdominal injuries.

There are various witness reports from the scene of more dead bodies having being found, but police would not give an official death toll.

Farid AbdulKadir, the head of disaster operations with the Kenya Red Cross Society, said: "I can confirm that four people are dead, our team has seen their bodies, but there could be many more dead," said

Witnesses said they feared many people might be trapped under the rubble of the building located on Ronald Ngala Street in the River Road area.

Bulldozers and ambulances arrived at the scene in central Nairobi, but the BBC's Karen Allen said army and rescue workers were getting caught up in crowds of onlookers and passers-by trying to search the debris.

A local man said the lower floors of the building had been filled with construction workers, and that workers had been adding floors to the top of the building.
