Traffic jams line the route between Beirut and the south after the ceasefire began at 04:00 local time (02:00 GMT).

The ceasefire calls for an initial two-month halt to fighting and requires Hezbollah to end its armed presence in southern Lebanon, while Israeli troops are to return to their side of the border. An international panel led by the United States will monitor compliance.

A ceasefire deal that could end more than a year of cross-border fighting between Israel and Lebanon's Hezbollah militant group won backing from Israeli leaders Tuesday, raising hopes and renewing difficult questions in a region gripped by conflict.
