Floods cause chaos across Africa

Floods cause chaos across Africa
Around a million people have been affected by floods in Africa, and more than 150 people have been killed after a long period of heavy rain.
Hundreds of thousands of people have been forced from their homes across 14 countries, and some towns and villages are completely underwater.
The United Nations said it is worried that more rain may be on the way, and the floods could lead to disease.
Ghana, Ethiopia, Sudan and Uganda are some of the worst hit countries.

The UN says 500,000 people had been affected in West Africa and a further 500,000 in Sudan, and the numbers were rising.
In Ghana the flood water has covered all the land normally used in that country to grow food.
George Azi Amoo, co-ordinator of Ghana's disaster management body, told the BBC: "Some villages and communities have now been totally wiped off the map of Ghana."
Dozens of people are thought to have been killed in Sudan, where the floods are the worst that most people can remember.
