Incident 
The incident happened when a bomb exploded targeting a Sri Lanka Army truck transporting military personnel, and it was followed by gun fire at Thandikulam, Vauniya on 19 November 2006. This bomb exploded 10 meters away from Thandikulam Agriculture Farm School which is managed by the Sri Lankan Government at around 9:45 am. Sri Lanka Police and Security forces alleged that this Claymore type directional mine was placed by the LTTE, which is a rebel group banned as a terrorist organisation by 32 countries including the United States, India and the member states of the European union. But LTTE denied these allegations. Casualties 
From this incident, five Sri Lanka Army soldiers including an officer were killed along with five students consisting of four Sri Lankan Tamils, one Sri Lankan Moor. Ten more students and four soldiers in the truck were wounded in the attack. Allegations towards responsibility 
Initially the Pro rebel LTTE media placed the blame on the government saying the army had entered the Thandikulam Agriculture Farm School, lined up the uniformed hostel students and shot at them blank range after the explosion and later it was followed by the international media agencies and by the Sri Lanka Monitoring Mission. But military sources denied these allegations and said, following a claymore attack on an army truck killing five soldiers, the LTTE opened fire on the troops using the farm school as a shield. The dead students were caught in the crossfire. Investigation
