COLOMBO, June 20: Separatist Tamil guerrillas detonated a landmine under a truck carrying food to troops in the rebels' former northern Jaffna stronghold, killing a soldier and wounding four, the defence ministry said today.

The explosion occurred at Urelu in the Jaffna peninsula, 320 km north of the capital Colombo, yesterday, a ministry statement said.

Jaffna, which was controlled by the separatist Liberation Tigers of Tamil Eelam (LTTE) for nearly a decade, was captured by government forces last year after a lengthy offensive.
