LIVE UPDATES: IDF Announces New Gaza Air Raid After Strikes Against Targets in Lebanon

"Early this morning, the IDF informed UNIFIL that they will begin an artillery response to yesterday’s rocket launches. Immediately after, UNIFIL personnel heard loud explosions around the city of Tyre. UNIFIL’s Head of Mission and Force Commander, Major General Aroldo Lázaro, is speaking with authorities on both sides of the Blue Line. Our liaison and coordination mechanisms are fully engaged. Both sides have said they do not want a war," the UN mission said in a statement on the website.

UNIFIL added that "the actions over the past day are dangerous and risk a serious escalation" and urged all parties "to cease all actions across the Blue Line now."

"This attack constitutes an injury to the ability of the terrorist organization Hamas to strengthen and arm itself," reads a translated statement issued by the agency.

"Lebanon categorically rejects any military escalation emanating from its territory and the use of Lebanese territories for operations that could lead to destabilization," Mikati told a meeting with Italian Defense Minister Guido Crosetto, as quoted by his office in a statement.

He added that the Lebanese authorities "condemn the rocket launches from the south of the country, and the army and UNIFIL forces are stepping up their investigation."

The prime minister said that all forces operating in the south of the country notified Beirut that they condemned the rocket launches.

UN peacekeepers in Lebanon were put on alert on Thursday after a rocket salvo fired from the country’s territory struck northern Israel, a source at the mission told Sputnik.

"Overall, we are on high alert. There is no information at the moment as to who fired the rockets," the source with the UN Interim Force in Lebanon (UNIFIL) said.

UNIFIL head Aroldo Lazaro said he was in contact with both Israeli and Lebanese authorities. The UN mission warned that the situation was "extremely serious" and urged everyone to avoid further escalation.

The Israel Defense Forces said they identified 34 rockets that were fired from Lebanon. Of those, 25 rockets were intercepted, while five landed in Israeli territory. Four launches are being investigated. At least three people were injured.

"A report was received of mortar attacks on the area near Metula from the Blue Line [the border separating Lebanon and Israel], after searches in the area, remains of ammunition were found," the IDF said in a statement.

The Israeli defense minister instructed the army to get ready for any options of retaliatory measures after the shelling from Lebanese territory. The final decision will be made by the meeting of military-political cabinet with Netanyahu at 8:30 pm local time.

"Fragile silence" has been established in the area following the attacks, according to the eyewitnesses.

'We condemn the launch of rockets from Lebanon and Gaza at Israel, our commitment to Israel security is iron clad, and we recognize Israel as legitimate right to defend itself against all forms of aggression," Patel said during a press briefing.

"Palestinian Hamas groups firing from Lebanon; Iranian involvement is also being explored. The state of Lebanon is responsible when fire is fired from its territory," Hagari said, as quoted by the radio.

"First day of Passover. As we sit at the holiday table, family and friends, Israel is facing rockets from south and north. This is not a coincidence. No one should test us, we will take all necessary measures to defend our country and people. I call on the international community to issue a clear statement against those responsible for the attacks on Israel," Cohen tweeted.

Israel’s Iron Dome system has intercepted 15 out approximately 30 rockets that were fired from the Lebanese territory over the past one hour, the Israeli military’s official radio station, Army Radio, reported on Thursday.

The airspace is closed for civilian aircraft in northern Israel, the Army Radio added.

Prime Minister Benjamin Netanyahu was "receiving continuous updates about the security situation and will conduct an assessment with the heads of the security establishment," his office said.
