Kenyan police on Tuesday in Nairobi confirmed that flooding sparked by heavy rains on Monday night killed 12 people in Nairobi.
Benson Kibue, Provincial Police Commander, said the wall of a mosque collapsed on shanty dwellings in Fuata Nyayo slum, and killed 10 people.
He said two other victims were swept away by floods.
Kibue said the flooding, which has left major roads submerged, was believed to have been made worse by blockages in the drainage system in several parts of the city.
