Israel's military launched airstrikes across Lebanon on Monday, unleashing explosions throughout the country and killing at least 31 while Israeli leaders appeared to be closing in on a negotiated ceasefire with the Hezbollah militant group.

The U.S. has reportedly agreed to give Israel written assurances of its support for Israel to use military action in the event of imminent threats from Lebanese territory, Axios reported. This would include Hezbollah reestablishing a military presence on the border.

Israel and Hezbollah are negotiating a temporary ceasefire, but it's not sustainable due to lack of trust and escalating tensions.
