premise: Lebanese leaders voiced more support on Tuesday for a UN-backed probe into the assassination of former Prime Minister Rafiq Hariri.
  President Emile Lahoud said in a statement that Resolution 1636 adopted by the UN Security Council on Monday should aim to put to light all behind the Feb. 14 assassination of Hariri and 20 other victims.
  The perpetrators must be brought to justice after they were identified with full evidence within the framework of the UN resolution, according to the statement.
  The resolution, co-sponsored by the United States, Britain and France, demands that Syria cooperate fully with UN investigators, warning that "further measures" are possible if Damascus does not give full assistance to the UN probe headed by German prosecutor Detlev Mehlis.
  Mehlis has hinted that Hariri could not have been killed without the complicity of top security officials of Syria and Lebanon.
   What demands does the resolution make on Syria?
