The UNHCR says it is alarmed by a dramatic rise in the number of new refugee arrivals from Somalia into Kenya. Over the past two weeks the Dadaab refugee complex in northern Kenya has received more than 20,000 Somali refugees. The new arrivals are mostly farmers and animal herders from Lower Juba and the city of Dhobley. During 2010, Dadaab received an average of 6,000 to 8,000 Somalis every month. This year the monthly average has increased to 10,000 refugees.
