Lebanon's state-run National News Agency reported at least 16 people were killed in Israeli airstrikes, which the Israeli military said were ongoing.

Continued fighting in Lebanon could unravel the newly signed deal, which calls for an immediate halt to military operations "on all fronts, including in Lebanon," where Israel has been battling the Iran-backed Hezbollah militant group, and for ensuring Lebanon's "territorial integrity and sovereignty."

Israeli Prime Minister Benjamin Netanyahu, who faces elections later this year, has refused to withdraw, saying Israeli forces will remain in Lebanon until the threat from Hezbollah has been eliminated.

The attacks came as planned talks in Switzerland between Iran and the United States over their efforts to reach a permanent end to the Iran war were delayed. 

US Vice President JD Vance on Thursday put off his trip to Switzerland where he had been set to lead the talks. The White House blamed logistical issues, but the announcement came after a report from Al-Mayadeen, a pan-Arab satellite channel that is politically allied to Hezbollah, that Iran was delaying sending its delegation to Switzerland over Israel's ongoing military campaign in Lebanon.
