Troops opened fire and killed at least two people among tens of thousands of people rioting over high food prices in Somalia's capital Monday, AP quoted a doctor and witnesses as saying. Several people also were injured in the protest in Mogadishu. The Somali protesters included women and children, who marched to protest the refusal of traders to accept old 1,000-shilling notes, blaming that for skyrocketing food prices. Tens of thousands of people quickly took to the streets, hurling stones that smashed the windshields of several cars and buses. Rocks also were thrown at shops, and chaos erupted at the capital's main Bakara market. Hundreds of shops and restaurants in southern Mogadishu closed their doors for fear of looting. Dr. Dahir Dhere said one man wounded in the protests died on the way to an operating room at the capital's main Medina Hospital.
