Unidentified assailants lobbed hand grenades at a government farm in eastern Sri Lanka on Sunday, killing four Tamil Tiger rebels, the military said. Two other rebels were wounded in the attack by a group traveling in a car, military spokesman Brig. Daya Ratnayake said. He said it was unclear who was behind the attack or why the Tamil rebels were at the farm in Trincomalee, about 230 kilometers (140 miles) northeast of Colombo, according to a report of The Associated Press.
