Lebanese children leaned out of cars flashing victory signs on Friday as they bumped across a makeshift bridge erected overnight across the Litani River after a truce with Israel.
Nearly a quarter of Lebanese have been forced from their homes, ordered by Israel to leave as it levelled villages and city districts and sent in troops over six weeks of war.
Israel says it has avoided targeting civilians in a military campaign it described as necessary to protect its own people from Lebanon's Iran-backed Hizbollah group.
A 10-day ceasefire announced on Thursday is now bringing respite, allowing many of the displaced to return to what remains of their homes while they pray for a lasting truce.
But tens of thousands will be unable to go back - their homes in ruins or lying in areas still held by Israel's military.
