A cease-fire between Israel and Hezbollah brokered by the U.S. and France took effect in Lebanon early Wednesday, raising hopes of ending more than a year of cross-border strikes and a full-scale war that has killed thousands.

The new cease-fire also gives an oversight role to the United States, which Iran and Hezbollah have long railed against for its staunch support for Israel. Iran and Hezbollah would have only accepted such an arrangement if they were desperate to stop the war, analysts said.
