A ceasefire between Israel and the Lebanese militant group Hezbollah has held up for over a month, even as its terms seem unlikely to be met by the agreed-upon deadline.

Israel warned the country’s ceasefire with Hezbollah could collapse if the U.S.-designated terrorist group does not abide by the conditions of the deal.
