US special envoy Amos Hochstein said Tuesday in Beirut that an end to the Israel-Hezbollah war was "now within our grasp" as he met officials to discuss a truce plan largely endorsed by Lebanon.

The US and France have spearheaded efforts for a ceasefire, which escalated in late September after nearly a year of deadly exchanges between Hezbollah and Israeli troops.

Israel expanded focus of its operations from Gaza to Lebanon, vowing to secure its northern border to allow tens of thousands of people displaced by the cross-border fire to return home.

After meeting with Hezbollah-allied parliament speaker Nabih Berri, who has led mediation on behalf of the group, Hochstein told reporters he saw "a real opportunity" to end the fighting.

"I'm here in Beirut to facilitate that decision, but it's ultimately the decision of the parties... It is now within our grasp."

Berri told pan-Arab daily Asharq al-Awsat after the meeting that "the situation is good, in principle", adding his team and US representatives still had "some technical details" to settle.

Hochstein also met Lebanese Prime Minister Najib Mikati and army chief Joseph Aoun. A Lebanon-based diplomat, requesting anonymity, said "progress" had been made in the talks.

A Lebanese official said the government had "a very positive view" of the truce plan.

But Prime Minister Benjamin Netanyahu said Monday that Israel would continue military operations against Hezbollah even if a ceasefire was reached.

"We will be forced to ensure our security in the north (of Israel) and to systematically carry out operations against Hezbollah's attacks... even after a ceasefire", to keep the group from rebuilding, he told parliament.

Hezbollah began its cross-border attacks in support of its ally Hamas following the Palestinian group's assault on Israel on October 7, 2023, which sparked the war in Gaza.

Hamas's attack resulted in the deaths of 1,206 people, mostly civilians, according to an AFP tally of Israeli official figures.

The health ministry in Hamas-run Gaza said the death toll from the resulting war had reached 43,972 people, the majority civilians. The United Nations considers the figures reliable.

Of 251 hostages seized during the October 7 attack, 97 remain in Gaza including 34, the Israeli military says are dead.

Netanyahu, in a video showing him inside Gaza and wearing a flak jacket and helmet, on Tuesday offered a $5 million reward to anyone in the territory "who brings out a hostage".

Since expanding its operations to Lebanon in September, Israel has conducted extensive bombing campaigns primarily targeting Hezbollah strongholds.

Israel has also sent ground troops into southern Lebanon, where it said Tuesday one soldier had been killed in combat and three wounded.

More than 3,544 people in Lebanon have been killed since the clashes began, authorities have said, most since late September.

Among them were more than 200 children, according to the UN. Lebanon's army said three soldiers were killed when Israel struck their position in south Lebanon on Tuesday.

Hezbollah has continued to launch rockets, drones and missiles into Israel almost daily.

The group said it fired guided missiles Tuesday night at Israeli forces in southern Lebanon.

In a statement, Hezbollah said it wounded Israeli soldiers in a guided missile attack in the border town of Markaba before firing a second at an infantry unit that came to remove the wounded -- then targeting a third unit that came to their aid.

There was no immediate reaction from Israeli authorities.

On Tuesday, Israel's military said some 40 projectiles were fired into central and northern Israel, lightly wounding four people.

That followed salvos on Monday that killed one woman in Shfaram and wounded 10 people there and five in Israel's commercial hub Tel Aviv.

Hezbollah said Tuesday it had launched "a salvo of missiles" at the Glilot military intelligence base in the Tel Aviv suburbs.

It said it also attacked Israeli troops in four places in south Lebanon, including near the flashpoint town of Khiam.

The United Nations Interim Force in Lebanon (UNIFIL) later said four Ghanaian peacekeepers were wounded when a rocket, "fired most likely by non-state actors", hit their base.

Another base in Shamma "was impacted by five rockets", UNIFIL said, and elsewhere "an armed person directly fired at" a patrol.

It did not report the number of wounded or specify who was behind those incidents.

Israel's military accused Hezbollah of firing on the peacekeepers.
