At least 42 people were killed in Kenya when a dam broke north of the capital Nairobi in Mai Mahiu district, the local governor told AFP, as the country was hit by deadly torrential rains.

“42 dead is a provisional count. There are others trapped in the mud that we are working to pull out,” Governor Susan Kihika said.

Earlier today, Kenyan authorities announced the postponement of the opening of schools for a week, due to heavy rains due to the El Nino climate phenomenon, which have caused devastating floods in the east African country.

El Niño is a natural climate phenomenon generally associated with global warming — causing droughts in some areas, excessive rainfall in others.
