The Tigers fired mortars and opened fire with small arms at the soldiers manning a check post the sources said.
The SLA retaliated by firing shells towards LTTE held villages of Kannankudah and Kurinjamunai in the western hinter land.
Following the incident the Tigers and SLA exchanged mortar fire for nearly two hours. Some of the mortars fired by the Tigers fell near Vavunathivu SLA camp and Sri Lanka Air Force base in Batticaloa, the sources said.
