A ceasefire between Israel and Hezbollah has begun, marking a notable step forward in diplomatic efforts in the region. The deal, brokered by the US and France, will see a 60-day halt to the fighting and allow tens of thousands of people on both sides of the border to return home. Israel will gradually withdraw its forces from Lebanon as Hezbollah leaves its positions and retreats north of the Litani River. The Lebanese army will take control of the territory to prevent Hezbollah from rebuilding infrastructure. There is disagreement over whether Israel has the right to attack Hezbollah if the militants break the agreement.
