Somali refugees seek shelter in Dadaab camp after fleeing a prolonged drought in Somalia, near the Kenyan border with Somalia, August 20, 2011. Dadaab, with roughly 400,000 refugees, Dadaab is the largest refugee camp in the world. The camp is grossly over capacity, and the refugees experience an ever-shrinking access to essential services such as water, sanitation, food and shelter, also because they have been sharing their rations with the new arrivals. At the current pace of arrival MSF estimates that the camp's population will total 500,000 before the end of 2011, and living conditions are only expected to deteriorate further. Without a long-term solution in sight, Médecins Sans Frontières (MSF) is deeply concerned about the fate of the hundreds of thousands of people who seek refuge in Kenya due to the ongoing conflict in Somalia combined with a looming nutritional crisis after several years of drought. The horn of Africa is suffering one of the worst droughts in years, displacing thousands, and killing others through severe malnutrition.The horn of Africa is suffering one of the worst droughts in years, displacing thousands, and killing others through severe malnutrition.
