Somali Famine Refugees Seek Aid In Mogadishu
MOGADISHU, SOMALIA - AUGUST 19: A young malnourished girl breathes in oxygen at a Turkish field hospital on August 19, 2011 in Mogadishu, Somalia. The tented hospital, opened this week by the Turkish Ministry of Health, is located next to a large camp for Somalis displaced by famine and drought. Some 100,000 Somalis have fled famine conditions in the countryside to Mogadishu in the last three months, according to the UN, setting up makeshift shelters in camps throughout the capital.
