Kenyan flying doctors medics help, upon arrival, one of the five Ugandan African Union peacekeepers injured in Mogadishu, Somalia, at the Willison Airport in Nairobi, May 16, 2007. A remote-controlled bomb killed four Ugandan peacekeepers and a civilian in the Somali capital Mogadishu on Wednesday as Islamist militants followed through on a threat to wage an Iraq-style insurgency. Five peacekeepers and two children were also wounded in the attack on the African Union (AU) convoy, which an AU security source said was the first of its kind against the 1,600-strong Ugandan contingent -- who had previously only been shot at.
