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

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.

A ceasefire proposal agreed to by Lebanon and Israel stipulates that only "official military and security forces" in Lebanon are authorised to carry arms in the country, according to a copy of the deal dated on Tuesday and seen by Reuters on Wednesday.
