Under the terms of the deal, Israel will gradually withdraw from Lebanon, while Hezbollah isn’t allowed to rebuild near the border. But will the ceasefire hold?

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 deal went into effect on Wednesday between Israel and Lebanon’s Hezbollah militant group. Here's what to know.

Under the ceasefire, southern Lebanon is to be cleared of Hezbollah, who will retreat north of the Litani River and Israel, which is to withdraw from Lebanon to the south of the Blue Line. The Lebanese Armed Forces (LAF) are to deploy to monitor the south alongside the UN peacekeepers, UNIFIL.

Prime Minister Benjamin Netanyahu called Hezbollah firing on a military site around the contested border was a "serious violation" of the ceasefire, and said Israel would "respond strongly."
