Israel unleashed its largest wave of airstrikes across Lebanon since agreeing to a ceasefire with Hizbollah last week, killing at least 11 people on Monday after the Lebanese group fired a volley of projectiles as a warning over what it said were Israeli truce violations.

The projectiles were apparently the first time that Hizbollah took aim at Israeli forces after the 60-day ceasefire went into effect last Wednesday.

The increasingly fragile truce aimed to end more than a year of war between Hizbollah and Israel - part of a wider regional conflict sparked by the devastating Israel-Hamas war in Gaza.

In the United States, President-elect Donald Trump demanded the immediate release of Israeli hostages held by the Palestinian Hamas group in Gaza, saying on social media that if they are not freed before he takes office in January there would be "HELL TO PAY.'

It was not immediately clear whether Trump was threatening to directly involve the US military in Israel's ongoing war in Gaza.

The US has given Israel crucial military and diplomatic support throughout the nearly 15-month conflict.

Lebanon's Health Ministry said an Israeli airstrike on the southern village of Haris killed five people and wounded two while another airstrike on the village of Tallousa killed four and also wounded two.

Israel's military carried out a string of airstrikes late Monday against what it said were Hizbollah fighters, infrastructure and rocket launchers across Lebanon, in response to Hizbollah firing two projectiles toward Mount Dov a disputed Israeli-held territory known as Shebaa Farms in Lebanon where the borders of Lebanon, Syria, and Israel meet.

Israel said the projectiles fell in open areas and no injuries were reported.

Hizbollah said in a statement that it fired on an Israeli military position in the area as a "defensive and warning response' after what it called "repeated violations' of the ceasefire deal by Israel. It said complaints to mediators tasked with monitoring the ceasefire "were futile in stopping these violations.'

Before the Hizbollah projectiles, Israeli carried out at least four airstrikes and an artillery barrage in southern Lebanon, including a drone strike that killed a person on a motorcycle, according to Lebanese state media. Another strike killed a corporal in the Lebanese security services.

Israel has said its strikes are in response to unspecified Hizbollah violations, and that under the ceasefire deal it reserves the right to retaliate.

Lebanon's parliament speaker, Nabih Berri, accused Israel of violating the truce more than 50 times in recent days by launching airstrikes, demolishing homes near the border and violating Lebanon's airspace.

Officials in the US - which along with France helped broker the truce and heads a commission meant to monitor adherence to the deal played down the significance of Israeli strikes.

White House national security spokesman John Kirby said, "Largely speaking, the ceasefire is holding.'

"We've gone from dozens of strikes down to one a day maybe two a day,' Kirby told reporters, referring to Israeli strikes.

"We're going to keep trying and see what we can do to get it down to zero.'

Under the deal, Iran-backed Hizbollah has 60 days to withdraw its fighters and infrastructure from southern Lebanon.

During that time, Israeli troops are also to withdraw to their side of the border.

In a post on his Truth Social site, Trump called for Palestinian group Hamas to free all of the roughly 100 Israeli hostages still held inside Gaza, around two-thirds of whom are believed to be alive.

If not, Trump said, "Those responsible will be hit harder than anybody has been hit in the long and storied History of the United States of America.
