Iran live updates: Trump threatens Iran infrastructure strikes if talks fail

Israeli Prime Minister Benjamin Netanyahu said Sunday that he had instructed the Israeli military to deepen its incursion into southern Lebanon to expand the "security zone in order to finally thwart the threat of invasion and to keep the anti-tank missile fire away from our border."

Speaking during a visit to the Israel Defense Forces Northern Command, Netanyahu said that in addition to three buffer zones created - in Syria, Gaza and Lebanon - "I have now instructed to further expand the existing security zone [in Lebanon] in order to finally thwart the threat of invasion and to keep the anti-tank missile fire away from our border.

Netanyahu also said that the buffer zone in Gaza is "more than half of the area of the strip."

"We are striking with tremendous force at Iran and its proxies," Netanyahu said, adding that Iran, Hezbollah and Hamas "are no longer terrorist armies that threaten our existence. These are defeated enemies, who are fighting for their existence."

The IDF said Saturday morning that its strikes on Hezbollah infrastructure continued across Lebanon, after targeting dozens of sites in the south of the country overnight.

The IDF also claimed that a targeted strike in the Lebanese capital of Beirut on Friday had killed two senior Hezbollah officials, Ayyoub Hussein Yaacoub and Yasser Mohammad Mubarak.

Ten members of the Kuwaiti military were injured in an Iranian attack on a Kuwaiti military base in the last 24 hours, according to a statement from the Kuwaiti army posted Sunday on X.

"During the past 24 hours, the Armed Forces detected 14 hostile ballistic missiles and 12 hostile drones within Kuwaiti airspace. This resulted in an attack on one of the Armed Forces' camps, causing injuries to 10 members of the Armed Forces, who are receiving the necessary medical treatment, in addition to material damage at the site," the statement said, in part.

Some privately owned warehouses were also damaged in attacks, though no casualties were reported, the statement further said.

"[T]he total number of hostile aerial threats detected has reached 307 ballistic missiles, two cruise missiles, and 616 drones" since the start of the U.S.-Israeli attacks on Feb. 28, according to the statement.

House Majority Leader Steve Scalise did not refute the possibility of American ground troops entering Iran when asked on Sunday, even as many in his party have voiced concerns about such a move.

"There are no boots on the ground today, but we're having a lot of conversations about what could happen next," Scalise told ABC News' "This Week." "But I think most people, most civilized people, recognize a nuclear-armed Iran is not an option that any of us want."

President Donald Trump is moving as many as 5,000 ground troops into the Middle East while declining to say whether they could ultimately be ordered into combat in Iran. Some 1,500 paratroopers from the Army's 82nd Airborne Division are preparing to deploy, according to a U.S. official. At the same time, Marine units based in Japan are sailing toward the region, with additional Marines from California potentially following in the weeks ahead.

Scalise said that he would not answer whether there would be widespread support from Republicans for ground troops in Iran because it has not yet happened.

"We're not at that point yet. Obviously you're seeing troop movement and we've got a number of bases in that region, too, that have been there for a long time," Scalise said. "So until that day comes, I'm not going to speculate, and you're not going to see the president go negotiate this in public."

Following a reported Iranian missile strike on a local industrial council in southern Israel on Sunday, fire and smoke were seen in the area as Israel's fire and rescue teams continued efforts to contain the blaze.

"Firefighters are working to contain the spread of the fire and cool tanks in the incident at the Ramat Hovav Council," a spokesperson for Israel's Fire and Rescue Services said in a statement.

"Due to the nature of the event and the presence of hazardous materials, the public is asked not to approach the area," the statement further said, adding that those in the vicinity should take shelter in protected buildings.

According to initial reports from Israel's national emergency medical services, there have been no confirmed casualties from the Iranian strike. However, teams were dispatched to treat several individuals who were injured while heading to protected areas, as well as others suffering from anxiety, according to the reports.
