A six-storey building has collapsed in a residential area of the Kenyan capital, Nairobi.
Media say at least three people have died but others have been pulled from the rubble alive.
Rescue workers are digging through wreckage amid what the Red Cross called "chaotic scenes".
It is not known how many people are trapped but television footage shows rescuers lifting rubble with their bare hands.
Recent heavy rain has caused landslides, washed away houses and flooded roads.
