Jerusalem, 27 Nov

The ceasefire between Israel and Lebanon's Hezbollah militants began early on Wednesday as a region on edge wondered whether it will hold.

The ceasefire announced on Tuesday is a major step toward ending nearly 14 months of fighting sparked by the ongoing war in Gaza between Israel and Hamas.

There were no immediate reports of alleged violations of the truce, and there were signs of celebration in Beirut. But Israel has said it will attack if Hezbollah breaks the agreement.

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.

Thousands of additional Lebanese troops and UN peacekeepers would deploy in the south, and an international panel headed by the United States would monitor compliance.

An Israeli military spokesman, in an Arabic-language X post in the first half-hour of the ceasefire, warned evacuated residents of southern Lebanon to not head home yet, saying the military remained deployed there.

The ceasefire began at 4 am Wednesday, a day after Israel carried out its most intense wave of airstrikes in Beirut since the start of the conflict that in recent weeks turned into all-out war. At least 42 people were killed in strikes across the country, according to local authorities.

The ceasefire does not address the devastating war in Gaza, where Hamas is still holding dozens of hostages and the conflict is more intractable.
