Hello, and welcome to NewsHour from the BBC World Service.
Coming to you live from London with me, Shawn Lay.
A ceasefire is not an end, but a beginning, the start of a process with both sides sensitive to any deviation from the agreement.
The US special envoy negotiating between Hezbollah and Israel, Amos Hochstein, who we'll hear from shortly, brokered the deal in conjunction with France, the former colonial power in Lebanon and still influential there.
Mr.
Hochstein stressed that the next 60 days should see a gradual withdrawal of Israel's defense forces from Lebanon's sovereign territory.
Hezbollah, in turn, is supposed to remove fighters and weapons from what's known as the Blue Line.
That's the unofficial border between Lebanon and Israel, and the litany river, about 30km to the north of that.
The Lebanese army will replace Hezbollah and ensure that any weapons or infrastructure used by the armed group can't be restored.
Both Israel and Lebanon have cautioned people displaced by the fighting not to rush back to their homes.
But thousands in southern Lebanon appeared to be ignoring that advice.
Throughout the day on Wednesday, lines of vehicles had backed up on the main highway that links Beirut, the capital, to southern Lebanon.
Some drivers displayed Hezbollah flags and posters showing the group's former leader, Hassan Nasrallah, who was killed in an Israeli airstrike.
And as we heard in the news, Israel has now imposed a nighttime curfew on those trying to travel into southern Lebanon.
The BBC's Lena Sinjab went to Dyer in southern Beirut today and spoke to one woman outside the ruins of her family home.
