The U.N. has consistently warned against the bloodbath scenario as we've watched the steady increase in civilian deaths over the last few months," U.N. spokesman Gordon Weiss said Monday.
"The large-scale killing of civilians over the weekend, including the deaths of more than 100 children, shows that that bloodbath has become a reality."
The first barrage struck the tiny sliver of northeast coast still held by the rebels Saturday evening and lasted through the night, health officials said.
Sunday evening, a new round of shelling — less intense than the first — pounded a newly demarcated "safe zone" where the government had urged civilians to gather, said Shanmugarajah.
A total of 393 people were either brought to the hospital for burial or died at the facility Sunday, while another 37 bodies were brought in Monday morning, he said. The dead included 106 children, he said. More than 1,300 wounded civilians came to the hospital as well.
However, the death toll was likely far higher, he said. Many of the dead were buried in the bunkers where they had taken refuge and then were killed, and many of the wounded never made it to the hospital for treatment.
"There were many who died without medical attention," Shanmugarajah said. "Seeing the number of wounded and from what the people tell me, I estimate the death toll to be around 1,000."
Reports of the fighting are difficult to verify because
the government bars journalists and aid workers from the war zone. The attacks marked the bloodiest assault on ethnic Tamil civilians since the civil war flared again more than three years ago.
U.N. figures compiled last month showed that nearly 6,500 civilians had been killed in three months of fighting this year as the government drove the rebels out of their strongholds in the north and vowed to end the war.
Human Rights Watch, Amnesty International and other rights groups called on Japan, the largest international donor to Sri Lanka, to press the U.N. Security Council to urgently address the civil war here.
"Formal meetings of the Security Council must be held urgently so that the council can take the necessary measures to address the humanitarian and human rights crisis," the groups said in a letter to Japan's prime minister.
