Kenyan camp strained from new refugee arrivals

Experts are now warning that the drought in the Horn of Africa will last for a few more months, raising the prospect of yet more people arriving from Somalia at the Dadaab refugee camp in Kenya.

It is the world's largest refugee camp and some of the occupants have been living there for decades, including Somalis who fled civil war and an earlier drought in their own country in the 1980's.
