Suspected Tamil Tiger rebels have killed up to 10 soldiers and wounded eight others in northern Sri Lanka, when they set off a powerful landmine in the Jaffna peninsula. A military official says the soldiers were ambushed with a Claymore mine at Puloly, where 18 soldiers were killed in two similar attacks earlier this month. Four days ago, the Tigers were accused of another ambush in the island's north-west, killing at least 15 sailors and wounding more than a dozen others.
