A suicide bomber detonated his explosives near a moving convoy of African Union troops in Somalia's capital on Friday, killing himself and at least three people walking by, police officials said. Mogadishu police official Mohamed Abdi said the dead were civilians, and a spokesman for the African Union peacekeeping mission in Somalia -known as AMISOM- said two soldiers were wounded in the attack near Mogadishu's international airport. "We have two minor injuries. This is not something that can stop AMISOM from stabilizing Somalia," AP quoted spokesman Col. Ali Aden Houmed as saying. The military convoy was attacked as it returned from its regular patrol of stations in Mogadishu where African Union troops are based, he said. Two of the bomb victims died on the spot and another died of his wounds at a Mogadishu hospital, said Capt. Mohamed Hassan of Mogadishu police.
