Over 14 million people in east Africa are at risk of starvation due to a combination of drought and rising food and oil prices, international aid agencies have said.

Ethiopia is the country worst affected, with over 10 million people needing assistance following poor seasonal rains according to British charity Oxfam. However communities in Kenya, Uganda, Somalia and Djibouti are also at risk.

In Kenya the situation has been compounded by insect infestation in the north, where caterpillars have damaged pasture and stripped crops in some areas, and post-election violence, which hampered planting at the start of this year.
