Israel will occupy southern Lebanon up to the Litani River, an area Defense Minister Israel Katz on Tuesday described as a “security zone”, spelling out for the first time Israel’s intent to seize territory amounting to nearly a tenth of the country.

At a meeting with the military chief of staff, Katz said Israeli forces would “control the remaining bridges and the security zone up to the Litani,” a river that meets the Mediterranean about 30 km (20 miles) north of Israel’s border.

Lebanon’s Iran‑backed Hezbollah said it would fight to prevent Israeli troops from occupying the south, calling such a move an “existential threat” to the Lebanese state.

Senior Hezbollah lawmaker Hassan Fadlallah said any Israeli occupation south of the Litani would be met with resistance. “We have no choice but to confront this aggression and cling to the land,” he told Reuters.

Katz has previously warned Lebanon’s government it could lose territory if it failed to disarm Hezbollah, which drew Lebanon into the U.S.‑Israeli war on Iran when it fired into Israel on March 2.

Israel has repeatedly invaded Lebanon in recent decades, and occupied the south until 2000. Since March 13, it has destroyed five bridges over the Litani and demolished homes in border villages, actions it says are part of a campaign against Hezbollah.

Under international law, attacks on civilian infrastructure, including homes and bridges, are generally prohibited.

UN Spokesperson Voices Concern

Asked about Katz’s comments, United Nations spokesperson Stephane Dujarric said the rhetoric was “very much concerning.”

“This is the last thing we would want to see. This is the last thing the Lebanese people in the south would want to see,” he told reporters in New York.

Katz had said there could be no homes or residents in areas of southern Lebanon where there was “terror”, an apparent reference to Hezbollah.

For the second time this week, he compared the approach to Israel’s campaign in Gaza, saying buildings near the border were being demolished to create a defensive buffer.

Casualties Mount

Israel’s ambulance service said a woman in Israel was killed near the border with Lebanon following missile fire toward northern Israel on Tuesday, with two others wounded by shrapnel. It did not specify where the missile was fired from. Two Israeli soldiers have been killed in fighting in Lebanon since the war began.

Israel’s strikes across Lebanon have killed more than 1,070 people, including more than 120 children, 80 women and 40 medics, Lebanon’s health ministry says. It does not otherwise distinguish between civilians and militants.

More than one million people have been displaced by strikes and evacuation orders, though thousands remain in parts of the south.

Lebanon’s health ministry said a 15-year-old boy was killed early on Tuesday when Israeli troops carried out an incursion into the southeastern town of Halta and abducted a man. The Israeli military did not immediately respond to a request for comment.

Lebanon’s government did not comment on Katz’s statement and residents who have fled the south decried the silence.

“If our government isn’t standing with us, what is it we can do?” said Najib Hussein Halawi, who fled his hometown of Kfar Kila near the border.

Lebanon Tells Iranian Envoy to Leave

An overnight strike on an apartment southeast of Beirut killed three people, including a three-year-old girl, according to the health ministry. The blast tore open walls and scorched furniture in a neighboring apartment.

Its owner, Rawaa Eido, told Reuters that militants who expect to be targeted should not be staying in residential buildings. “We don’t have any political affiliation to anyone at all…Why – when they’re being targeted – do they want to hide in houses among people?” she said, in tears. There was no comment from the Israeli military.

Later on Tuesday, an Iranian missile was intercepted in Lebanese airspace by a launch from a foreign vessel off Lebanon’s shores, three security sources told Reuters. The Israeli military also said the missile was fired from Iran. Shrapnel landed in several Lebanese towns.

Lebanon on Tuesday declared the Iranian ambassador persona non grata and gave him until Sunday to leave, after ordering the departure of dozens of other Iranian nationals including diplomats this month. It said the move did not represent a severing of diplomatic ties with Iran.

Israeli Foreign Minister Gideon Saar praised the decision, while Hezbollah condemned it.
