JERUSALEM / BEIRUT / DAMASCUS - Hezbollah forces in Lebanon fired approximately 115 rockets into Israel early Sunday, with some reaching areas near the northern city of Haifa, extending their range to previously untargeted locations amid the ongoing conflict.

Israeli media reported that Hezbollah targeted a military airport located in the northern Jezreel Valley, triggering sirens across the region and in various areas of the occupied Golan Heights and Upper Galilee.

Buildings were damaged and cars caught fire near Haifa. The Israeli Magen David Adom emergency service said four people were injured by shrapnel, including a 76-year-old man who sustained moderate wounds, while the other three were lightly injured.

The Israeli military said in a statement that Hezbollah's rockets were fired toward "civilian areas" and that its defensive systems "are deployed in the area and on high alert to thwart threats."

The Israeli military carried out additional airstrikes in southern Lebanon on Sunday morning and vowed that its strikes "will continue and intensify against Hezbollah."

Following the rocket attack, Israel's Home Front Command announced that schools would be closed and gatherings and movements would be restricted in all areas north of Haifa.

Hezbollah claimed responsibility for the attacks, saying that they were targeting a military industry complex of Rafael, a weapons company.

The attacks, Hezbollah said, were the "initial response to the brutal massacre" on Tuesday and Wednesday.

Israel allegedly caused thousands of pagers and wireless devices to explode, killing at least 37 people, including civilians, and injuring thousands. An Israeli airstrike on the weekend in Beirut targeted a senior Hezbollah commander, killing at least 45 people.

Also before dawn, multiple drones approached Israel from the direction of Iraq. The Israeli military said they were intercepted before crossing into Israeli territory.

Hezbollah also targeted the Ramat David Airbase in northern Israel at dawn on Sunday with surface-to-surface missiles for the first time in response to Israeli attacks on Lebanese areas.

Israel had launched a new wave of airstrikes in Lebanon on Saturday evening, targeting Hezbollah rocket launchers and other installations, according to the Israel Defense Forces (IDF).

"Dozens of Israeli Air Force aircraft are currently striking terrorist targets and rocket launchers to remove the threat to Israeli civilians," IDF Spokesperson Daniel Hagari said.

The strikes followed reports of Hezbollah's preparations for significant rocket attacks on Israel, with Lebanese media releasing footage of large explosions.

Hagari announced new restrictions for civilians in northern Israel, extending from Haifa northward, as regional fighting intensifies. "We ask you to follow the Home Front Command guidelines," Hagari stated. "It is possible that in the immediate time frame, rockets and other threats may be launched at Israel."

The new guidelines, effective from 20:30 local time (1730 GMT), include limiting gatherings to 30 people outdoors and 300 indoors, permitting work only in protected spaces, and allowing educational activities to continue where safe spaces are available.

Northern Israeli cities near the Lebanese border such as Haifa, Akko, and Nahariya have reportedly closed the beaches.

These restrictions affect the Lower and Upper Galilee, Haifa Bay, Central Galilee, and parts of the Israeli-occupied southern Golan Heights.

Meanwhile, a displaced Syrian was killed Saturday morning in an Israeli airstrike targeting a motorcycle in southern Lebanon, according to Lebanese military sources.

The sources, who spoke anonymously, told Xinhua that an Israeli drone fired two air-to-ground missiles at a motorcycle on the road of Hamoul near the town of Naqoura, burning the motorcycle and killing its driver.

The body of the victim was transported by a civil defense vehicle to a hospital in the city of Tyre in southern Lebanon, the sources said.

The sources told Xinhua that Israeli warplanes and drones carried out three airstrikes Saturday morning on the outskirts of three border towns and villages in southern Lebanon, and Israeli artillery shelled eight towns and villages in southern Lebanon.

So far, the Israeli side has not commented on the attacks.

At least 31 dead

Also on Saturday, Lebanese Minister of Public Health Firass Abiad said at least 31 people, including three children and seven women, were killed, and 66 others injured in an Israeli airstrike on Friday targeting a building in the Jamous area of Dahieh in the southern suburbs of Beirut.

Hezbollah also issued separate statements mourning the death of 14 commanders who it said were killed in Friday's airstrike.

The Syrian Observatory for Human Rights reported Saturday that a Syrian woman and her child, both traveling from the rural area of Syria's Aleppo to Lebanon, died of injuries sustained in Friday's airstrike.

Since the Gaza war began in October last year, the total number of Syrians killed in Lebanon has reached 34, including eight women and three children, while injuries total 18, according to the war monitor.

Tension along the Israel-Lebanon border has escalated sharply following communications devices explosions in Lebanon earlier this week that killed 37 and injured 2,931.

These developments marked the latest escalation of ongoing conflict on the Israel-Lebanon border that began on Oct 8, 2023, when Hezbollah launched rockets at Israel to show support for Hamas in the Gaza Strip, prompting Israel's retaliatory artillery fire and airstrikes into southeastern Lebanon. The conflict has already caused heavy casualties and displaced tens of thousands on both sides.
