Tension prevails in the area and parents fear the latest LTTE attack, most violent of its kind to have caused trauma and fear psychosis among the children, defence sources said.

The reverberation caused due to the LTTE shelling was heard distances, ground sources said. Many including parents and children met with minor injuries while rushing for safety during the LTTE attack.
