A claymore mine was triggered by an unidentified person in Panichchankerni, 60 kilometres north of Batticaloa, Tuesday. No one was hurt in the explosion. An LTTE official in Batticaloa alleged that an informant working with the Sri Lanka army had set off the explosion. He said the improvised device may have been aimed at two local LTTE cadres who had passed the Panichchankerni bridge minutes before the explosion.
