At least five people have been killed in Syrian funeral processions, a day after 80 protesters died in the country's bloodiest day of the uprising so far. Snipers opened fire from rooftops as a funeral procession made its way to a cemetery, killing at least three mourners and wounding one in the Damascus suburb of Douma. Tens of thousands of mourners marched in the procession, setting off from a mosque in the northern suburb to the cemetery. Clerics in Damascus were heard using mosque loudspeakers to appeal on doctors to help anyone wounded in the attack. Two other mourners were killed in southern Syria as they joined funeral cortges headed for the town of Izra to bury scores of people killed on Friday by security forces, a human rights activist said.
