At least 22,000 Somali refugees have arrived in Kenya since the beginning of this year to join 130,000 others others who have lived in refugee camps in the remote, arid Dadaab area in the country's Northeastern Province since 1991. Although most of the new arrivals early this year fled because of food shortages after the drought, people also sought to escape the warfare that engulfed Mogadishu from February to June as the Union of Islamic Courts (UIC) fought and eventually dislodged an alliance of warlords from the city.
