A group allied with Sri Lanka's Tamil Tiger rebels threatened Monday to force the military and "traitors" from the country's Tamil-dominated northeast if violence continues against the ethnic group there. The statement from the Trincomalee Tamil Peoples Consortium followed a weekend of violence during which a Muslim mob beat two Tamil men to death in the northeastern city of Trincomalee. "The day when paramilitaries and traitors must run away from our land is not very far," the group said in its statement, carried on the rebels' official Web site. "When the anger of the Tamil people at these lowly acts bursts out, we warn that the traitors will be forced to run with the Sri Lankan military from our land." Sri Lankan troops and police stepped up security Monday following a spate of attacks blamed on the Tamil Tigers that killed 12 people over the weekend, a military official said.
