Malnutrition is worsening in the Somali capital of Mogadishu as fighting intensifies between Islamists and the country's weakened transitional government; the number of displaced people - already an estimated 600,000 - is also dramatically rising. Meanwhile, many Somalis are showing signs of mental health problems as the country's 17-year-long civil war takes its toll. The Islamists - dislodged by the Ethiopian-backed transitional government with covert U.S. help in 2006 - are fighting an Iraq-style insurgency with support from Eritrea.
