Mayors of several towns in southern Lebanon said the Israeli military had ordered them to force out the displaced who had escaped their Shia-majority towns, considered Hezbollah strongholds, during the war with Israel.

Since Lebanon was pulled into the Middle East war following Iran-backed Hezbollah's March 2 rocket fire on Israel, more than a million people have been displaced by Israeli strikes.

U.S. President Donald Trump told reporters on Monday that his envoys held talks with a senior official in the Iranian leadership and claimed the parties are in agreement on many points.

Trump walked back his threat to strike Iran's power plants on Monday, citing productive negotiations.

President Donald Trump said Monday that there are "major points of agreement" in U.S.-Iran talks which he said must result in Tehran giving up its nuclear ambitions and enriched uranium stockpile.

Iranian media said on Monday there were no negotiations between Tehran and Washington after US President Donald Trump announced talks towards ending the war.

"There are no talks between Tehran and Washington," said Mehr news agency citing Iran's foreign ministry, adding that Trump's statements were part of a push "to reduce energy prices".

President Donald Trump has extended his deadline for Iran to reopen the Strait of Hormuz, saying the U.S. will hold off on power plant strikes for five days.

Trump made the announcement on his Truth Social site Monday, hours ahead of a deadline later in the day.

Prime Minister Nawaf Salam has said that members of Iran's Revolutionary Guards are commanding Hezbollah's operations in the group's ongoing war against Israel.

In an interview Sunday with the Al Hadath network, Salam once again lashed out at Hezbollah for dragging Lebanon into the Middle East war by firing rockets on Israel.

The Israeli military has announced it was expanding its ground campaign against Hezbollah in Lebanon, warning of a lengthy operation, after Beirut condemned what it called Israel's flagrant violations of Lebanese sovereignty.

Israeli forces were ordered Sunday to destroy bridges they said were used by the Hezbollah to cross the Litani River, and Lebanese official media reported Israeli raids in the south.

The Israeli military on Monday said its own artillery fire killed an Israeli civilian a day earlier near the northern border with Lebanon, where its forces are fighting Hezbollah.

After opening an investigation, the military said "the initial findings suggest that the Israeli civilian was killed by IDF artillery fire conducted to support IDF soldiers operating in southern Lebanon".

Israel said it struck "Hezbollah" targets in south Lebanon on Sunday shortly after the military was ordered to destroy bridges allegedly used by the Iran-backed group across the Litani River.

Iran's military threatened on Sunday to completely shut down the strategic Strait of Hormuz if U.S. President Donald Trump acts on threats to target the country's power plants.
