Scores of government troops and Tamil Tiger rebels were killed on Tuesday, the second day of the Sri Lankan Armed Forces' offensive to capture Sampur and Mutur East overlooking Trincomalee harbour.
The government said that 66 Tamil Tigers were killed in the military operations, which were being carried out to "protect refugees from the LTTE".
The government said that the LTTE was preventing the resettlement of refugees by firing mortars and artillery on them.
The Sri Lankan Air Force had to take on the LTTE's gun placements in Eechchalampattu.
In the process of clearing Selvanagar, Thoppur and Mutur of the Tiger rebels, the army lost 13 of its men.
But the LTTE said it killed 50 soldiers even as it lost 12 of its own cadres.
The army said that in Muhamalai in Vavuniya district on Tuesday, the LTTE fired mortars on eleven lorries carrying 120 tonnes of food stuffs meant for the relief of war-affected people in the LTTE-controlled districts of Kilinochchi and Mullaitivu.
The crew of the trucks had to abandon their vehicles and run back, the army said.
But a spokesman of the International Committee of the Red Cross (ICRC), whose personnel were in Muhamalai, told Hindustan Times that it had not got any report of such an incident.
