Israel-Gaza-Lebanon updates: Netanyahu calls UN troops Hezbollah 'human shields'

Former Israeli Prime Minister Naftali Bennett called for a major attack on Iran, saying in a video posted to social media on Tuesday: "The opportunity must not be missed."

Israeli leaders say they are preparing a response to Iran's Oct. 1 ballistic missile barrage.

"Attack the Iranian nuclear program and the regime centers now," urged Bennett, who was prime minister from 2021 to 2022 and remains an influential voice in national politics.

An August poll by Israel's Channel 12 news found 38% of respondents would support Bennett's return as prime minister, versus 33% who wanted Netanyahu to remain in the post. Both men polled better than opposition leaders Benny Gantz and Yair Lapid.

The Israel Defense Forces announced that a fourth division joined its ground operation in southern Lebanon on Monday.

The 146th Division "began limited, localized, targeted operational activities against Hezbollah terror targets and infrastructure in southwestern Lebanon," the IDF said. The 146th was previously deployed along Israel's northwestern border with Lebanon in a defensive role, it said.

The IDF said the 146th Division is the first reserve division to be deployed into southern Lebanon. Its troops will be supported by the 213th Artillery Brigade and other units, the IDF said.

The 146th joins the 91st Galilee Division, 98th Paratroopers Division and 36th Division which are already in action in southern Lebanon.

The Israel Defense Forces said they struck more than 120 Hezbollah targets in southern Lebanon on Monday within an hour.

The airstrikes followed evacuation orders earlier Monday.

Over the past 48 hours, 190 airstrikes were recorded throughout Lebanon, primally in the south, according to the Lebanese Security Council. Forty-seven people were killed and another 207 injured, according to the Lebanese Ministry of Public Health.

Approximately 190 projectiles were fired by Hezbollah from Lebanon into Israeli territory on Monday, according to the IDF.

Vice President Kamala Harris and second gentleman Doug Emhoff marked the first anniversary of the Oct. 7 attack by planting a pomegranate tree -- a symbol of hope and righteousness in Judaism -- at the vice president's residence.

Harris said the tree will "remind future vice presidents of the United States, their families and all who pass through these grounds, not only of the horror of Oct. 7, but the strength and the endurance of the Jewish people."

The vice president underscored her pledge to make sure Israel has what it needs to defend itself.

Harris also said the world must "work to relieve the immense suffering of innocent Palestinians in Gaza who have experienced so much pain and loss over the year."

Emhoff, the first Jewish spouse of a president or a vice president, also spoke about the "incredibly challenging day for Jews."

"We are still hurting, and today feels just as raw as it did one year ago," he said. "What happened on Oct. 7 is seared into our souls."
