An international relief agency says months of chronic drought and food shortages in Kenya have led to violent clashes between nomadic tribes.
Oxfam International says the tribes are fighting over declining water and grazing resources. In a recent incident, more than 30 people died when nomads from neighboring Ethiopia carried out a raid in northeastern Kenya.
There have also been reports of violence between Kenya's Turkana tribe and the Karamajong tribe of neighboring Uganda.
The Kenyan government says possibly four million people are facing severe food shortages. Scores of people and thousands of livestock have already perished from starvation and other related illnesses.
Oxfam says the crisis in Kenya risks "turning into a catastrophe" unless relief efforts are increased.
