Sri Lankan Air Force jets on Wednesday bombed the Verugal river region and Sampur, both in Trincomalee district, in retaliation for the LTTE's closing the sluicegates of the Mavil Aaru dam since July 20.
The dam supplies water to 1,500 people cultivating over 30,000 acres of paddy land.
The pro-LTTE Tamilnet website reported that Kfir jets of the Air Force conducted three raids wounding two civilians and destroying two houses in the Verugal river area between 4.30 pm and 5.20 pm.
Later, at about 10 pm, residents of Trincomalee town reported that they heard sounds of aerial bombing from the Sampur area.
Sampur had been bombed twice before since April 25.
The government Peace Secretariat said in a statement that the closure of the sluice gates was in "blatant contravention of international law," and in violation of the Ceasefire Agreement.
A spokesman of the Nordic truce monitors was quoted by the BBC as saying that the LTTE had sent a letter to the government, stating its conditions for opening the sluice gates.
