COLOMBO, Jan 7 (SPA) -- Suspected Tamil Tiger suicide bombers sank a naval patrol boat off Sri Lanka's east coast early on Saturday and 13 of the 15 crew were missing, the navy said, in the worst attack at sea since a 2002 truce halted civil war. Nearby fishermen pulled two sailors alive from the water after the pre-dawn attack on the Israeli-built fast patrol boat just outside Trincomalee naval harbour, and the Navy was searching for the rest of the crew, all initially feared to have died. A Tamil Tiger boat had rammed their boat and exploded, destroying both vessels, a military source said. Reuters quoted Harbour police as saying that they had heard a loud explosion. --SPA 10 42 Local Time 07 42 GMT www.spa.gov.sa/317368
