The major aid giving countries have appealed to the Sri Lanka government and the LTTE to immediately stop fighting and resume negotiations to settle the ethnic conflict in the island.
The aid givers, US, EU, Japan and Norway, also called for independent international investigations of allegations of serious human rights abuses including the murder of 17 Sri Lankans working for a French NGO and the alleged killing of 100 Muslims in Eastern Sri Lanka by the LTTE.
Generally referred to as the Co-chairs of the 2003 Tokyo Donors' conference, the four countries said that both the Sri Lankan government and the LTTE " must make the utmost effort to prevent further escalation of violence and loss of life."
"Violence is not the way to resolve the ethnic conflict in Sri Lanka."
"The suffering inflicted on innocent civilians is intolerable," they said.
Expressing "serious concern" about the plight of the refugees, the Co-Chairs said that the two parties should "allow relief agencies to assist victims from all the three ethnic groups and to grant access to disputed areas."
There have been complaints by the Tamils that the Sri Lankan forces have been preventing aid convoys from reaching them.
"This is a matter of priority to avoid a humanitarian disaster," the Co-Chairs said.
They then went on to call for "independent international investigations" into the "serious" human rights abuses, including the murder of 17 local staff of a the French aid agency "Action Against Hunger" and the alleged killing of 100 Muslims by the LTTE.
