The UN Security Council backed the resolution unanimously.

Here's what it demands:

- A "full cessation of hostilities." Hizbollah is to stop fighting immediately and Israel is to halt all "offensive military operations."

- Deployment of up to 15,000 new troops for the U.N. Interim Force in Lebanon (UNIFIL) to monitor the truce.

- UNIFIL can "take all the necessary action to ensure that its area of operations is not used for hostile activities of any kind."

- The Lebanese government is to deploy troops in the south, now controlled by Hizbollah, and prevent any weapons flowing to the militia.

- Israel is to withdraw its forces from southern Lebanon when fighting stops in parallel with the deployment of Lebanese and U.N. troops.

- States are to bar the delivery of weapons or military equipment to "any entity or individual" in Lebanon, except the Lebanese army and U.N. troops.

- The preamble of the resolution, which carries less weight, calls for the unconditional release of Israeli soldiers abducted by Hizbollah in a cross-border raid. And it encourages settling the issue of Lebanese prisoners detained in Israel.

- UN Secretary General Kofi Annan is to develop proposals within 30 days for disarmament of militia and delineation of borders, including the disputed Shebaa farms area on the Israel-Syrian-Lebanon border.
