Israel's military said Friday its forces struck targets throughout southern and eastern Lebanon overnight into Friday as Hezbollah reported intense fighting in the area, threatening the nascent agreement between Iran and the United States to end their war.

Talks planned for Friday in Switzerland between Iran and the United States, which Vice President JD Vance had been scheduled to attend, found themselves postponed as the fighting intensified. Mediators worked to reschedule the meetings crucial for starting talks over a permanent end to the Iran war, with much of the attention focused on Lebanon, regional officials said.
