Sri Lankan ethnic Tamil victims of a shell attack wait outside a makeshift hospital in Tiger controlled No Fire Zone in Mullivaaykaal, Sri Lanka, Sunday. An all-night artillery barrage in Sri Lanka's war zone killed at least 378 civilians and forced thousands to flee to makeshift shelters along the beach, Sunday. The army and Tamil Tiger rebels blamed each other for the barrage, which left at least 1,100 people wounded. It is said, it was the bloodiest day seen in months of fighting.
