A bomb blast in northern Sri Lanka Monday has killed five people and wounded at least four others.
Police say the bomb, in the city of Trincomalee, was meant for a naval foot patrol. One of the dead and at least three of the wounded were navy officers.
Officials have blamed the attack on Tamil Tiger rebels, who are fighting for a homeland for minority Tamils.
In a separate attack Monday, military officials say five sailors were wounded when seaborne Tigers fired on a naval gunboat in waters north of Trincomalee.
Earlier in the day, a pro-rebel Web site reported the Tigers had moved fighters along the island's northeastern coast to Trincomalee.
The incidents are the latest to shake a four-year-old ceasefire between the government and Tamil Tigers.Some information for this report was provided by AFP, AP and Reuters.
