UN Security Council on Thursday asked the Tamil Tigers to immediately surrender, renounce terrorism and join the political process through dialogue to put an end to the decades old ethnic conflict in Sri Lanka.

"We demand that the LTTE immediately lay down arms, renounce terrorism, allow a UN assisted evacuation of the remaining civilians in the conflict area, and join the political process through dialogue," UNSC President Claude Heller, who is also Mexican Ambassador, told reporters on Thursday after a meeting convened at the request of France.
