Somalia's President Sheikh Sharif Ahmed addresses a news conference in Mogadishu, September 19, 2009. The United Nations is investigating the use of its vehicles by suicide bombers who killed 17 African Union peacekeepers at their main base in the Somali capital, a senior official said on Saturday. President Ahmed said the attack, which followed Monday's killing of one of Africa's most wanted al Qaeda suspects by U.S. special forces, would not deter his government and he called on the world to send it more help.
