Flooding caused by heavy rains has affected large areas of Kenya including the capital, Nairobi. At least 11 people have been killed and more than 17,000 are displaced.

The rainy season that began in mid-March has damaged homes and farmland.

Those affected are appealing for urgent government assistance as hunger and the risk of disease loom.

The Kenya Red Cross is helping those who have been forced from their homes and has advised those in low-lying areas to seek shelter.

The rain is forecast to last until early next week.
