A six-storey building has collapsed in a residential area of the Kenyan capital Nairobi as heavy rain plays havoc across the country. At least three people have died, KTN television reported, 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. The rainfall has caused landslides, washed away houses and flooded roads. The pictures showed rescuers lifting rubble with their bare hands. At one point the crowd erupted into cheers when a baby was pulled out alive. According to KTN, more than 50 people have been rescued so far. There has been no independent confirmation of the death toll. In another county, two boys are missing after going herding, according to the Red Cross. Earlier on Friday at least three people were killed when a wall collapsed in an area of Nairobi, according to local media. President Uhuru Kenyatta last year ordered an audit of all the buildings in the country after a spate of collapses. The same area of Nairobi saw another collapse early last year, with at least two people killed. Poor construction standards are frequently blamed for such incidents.
