UNITED NATIONS - The UN refugee agency said Friday it urgently needs 45,000 more tents as more Somalis continue to arrive in Kenya after fleeing drought, famine and conflict in their homeland. More than 70,000 Somali refugees have arrived at the three camps that make up Kenyas Dadaab refugee complex during June and July, bringing the overall population there to 440,000, according to the UN High Commissioner for Refugees (UNHCR). As well as needing food and water, these new arrivals urgently need proper shelter, medical help and other basic services, UNHCR spokesperson Adrian Edwards told a news conference in Geneva, according to a news release issued at UN Headquarters in New York. The agency has moved thousands of tents to Dadaab since the current crisis began but they are still not sufficient for the growing refugee population. Some 3.7 million people, nearly half the Somali population, are now directly at risk of famine and tens of thousands have already perished.
