JERUSALEM: Prime Minister Benjamin Netanyahu warned Lebanon Tuesday it could face destruction "like Gaza" as Israel ramps up its ground offensive against Hizbollah along the southern section of the Lebanese coast.

Netanyahu's stark warning came as the Israeli military deployed more troops and urged civilians in coastal areas to evacuate.

"You have an opportunity to save Lebanon before it falls into the abyss of a long war that will lead to destruction and suffering like we see in Gaza," Netanyahu said in a video address directed to the people of Lebanon.

"I say to you, the people of Lebanon: Free your country from Hizbollah so that this war can end."

Hizbollah earlier said it fired rockets at the Israeli port city of Haifa, after the Israeli military reported 85 projectiles crossing from Lebanon.

It threatened more rocket fire on Israeli towns and cities if the bombing of Lebanese population centres continues.

Israel expanded operations in Lebanon nearly a year after Hizbollah began exchanging fire in support of its ally, Hamas, following the Palestinian group's deadly attack on Israel on October 7, 2023.

While battling Hamas in Gaza, Israel has vowed to secure its northern border with Lebanon to allow tens of thousands of Israelis displaced by Hizbollah's cross-border fire to return home.

Both Hamas and Hizbollah have pledged no let-up against Israel, and on Tuesday Hizbollah's deputy leader Naim Qassem said the group would make it impossible for Israelis to return to the north.

Israel launched a wave of strikes against Hizbollah strongholds in Lebanon on September 23, leaving more than 1,150 people dead since then and forcing more than a million to flee.

Israeli attacks have mainly targeted Hizbollah strongholds in southern and eastern Lebanon, as well as south Beirut.

While the coast has not been spared, Israel's latest evacuation warning suggests it is extending its offensive northwards.

On its Telegram channel, the Israeli military said its 146th Division began "limited, localised, targeted operational activities" against Hizbollah targets and infrastructure in southwestern Lebanon.

A day earlier, the military had warned people to stay away from the southern part of Lebanon's Mediterranean coast, with a spokesman saying Israel would "soon operate in the maritime area against Hizbollah's terrorist activities" south of the Awali river.

In Sidon, fishermen stayed ashore and the seafood market was unusually quiet.

"Fishing was the way we supported our children. If we don't go out to sea, we won't be able to feed ourselves," said fisherman Issam Haboush.

The Israeli military said it hit Hizbollah's south Beirut bastion, where a strike last month killed the militant group's leader Hassan Nasrallah.

It later said it dismantled a Hizbollah tunnel leading from Lebanon into Israel.

Hizbollah said it repelled Israeli troops who "infiltrated from behind" a UN peacekeepers' position in the southern border village of Labboune.

Hizbollah's deputy leader said despite Israel's "painful" strikes, the group's leadership structure was in order and its military capabilities were "fine."

Israeli Defence Minister Yoav Gallant said Hizbollah was " a battered and broken organisation, without significant command and fire capabilities, with a disintegrated leadership following the elimination of Hassan Nasrallah."

Gallant had been due to visit Washington for talks on Wednesday with Pentagon chief Lloyd Austin that were expected to focus on Israel's response to Iran's missile attack last week.

But the Pentagon confirmed the visit had been postponed, after Israeli media reported Netanyahu had demanded that the cabinet decide on the action to be taken before the minister's departure.

The expansion in the fighting came a day after Israelis and people around the world marked the first anniversary of Hamas's October 7 attack on Israel.

For families of the bereaved, as well as relatives of 251 people taken hostage into Gaza, the pain was especially acute.

Of the total number, 97 hostages are still being held, including 34 the Israeli military says are dead.

Hamas's October 7 attack resulted in the deaths of 1,206 people, mostly civilians, according to an AFP tally based on Israeli official figures, which include hostages killed in captivity.

Israel's retaliatory military offensive has killed 41,965 people in Gaza, most them civilians, according to figures from the Hamas-run territory's health ministry that the United Nations has described as reliable.

The conflict has since spread across the wider region, with Israeli forces battling Iran-backed groups in Lebanon, Yemen and Syria.

The Syrian government said seven civilians were killed in an Israeli air strike in Damascus Tuesday, that a war monitor said targeted a building used by Iran's Revolutionary Guards and Hizbollah.

Electrician Adel Habib, 61, who lives in the building, said he was on his way home when the strike hit.

"These were the longest five minutes of my life until I heard the voices of my wife, children and grandchildren."

A year since the start of Israel's military offensive in Gaza, swathes of the territory have been reduced to rubble, and nearly all its 2.4 million residents have been displaced at least once.

The International Committee of the Red Cross said that after a year of war, civilians in Gaza were still living in ramshackle shelters and struggling to find food.

"They still can't return to their homes. They still don't know whether their homes are standing," ICRC spokeswoman Sarah Davies told AFP in an online interview from Gaza.

On Tuesday, the territory's civil defence agency said an Israeli strike on a refugee camp in the centre of the Gaza Strip killed at least 17 people.

Many in Gaza just want the war to end.

"I have grown old while watching my children hungry, scared, having nightmares and screaming day and night from the sound of the bombing and shells," said Israa Abu Matar, a 26-year-old displaced woman.
