Mogadishu residents carried wounded Somalis on wheelbarrows as bullets flew over the battered capital on Thursday in a new flare-up of violence between rival militias that killed up to 30 people. Firing mortars, grenades and anti-aircraft guns, militia linked to Islamic courts squared off with gunmen for a self-styled anti-terrorism coalition of warlords, in a resumption of the worst violence in Mogadishu for a decade. Scores fled the fighting, which erupted on Wednesday and intensified Thursday morning as it spread across Mogadishu. The streets were full of terrified old people and children, witnesses said. “There are so many people dead, I saw nearly 30 dead and over 40 wounded,” resident Abdifatah Abdikadir told Reuters by telephone from the Kilometre Four area in southern Mogadishu. “People are being carried on wheelbarrows to the hospital with broken limbs and gunshot wounds. It’s going from bad to worse.”
