The fresh 120 rocket attacks came hours after the Lebanese group Hezbollah said it would support "any measure" the Palestinian groups could take against Israel following clashes at Al-Aqsa on Jerusalem's Temple Mount.
The Israeli prime minister is currently moving to the Ministry of Defense to coordinate the defense of the attacks and prepare the Israeli response.
Sirens are sounding in the towns of Bezet and Shlomi in the western Galilee, near the border with Lebanon.
It is known that Israeli air defense systems were able to intercept most of the rockets, however, at least 5 rockets exploded in Israeli territory, causing injuries.
A video has surfaced online showing smoke trails from Israeli Iron Dome interceptor missiles.
The rescue service said one person was slightly injured by shrapnel and a woman was injured while running for cover.
Prime Minister Benjamin Netanyahu received information about the incident, which fell during the Jewish Passover holiday season.
Netanyahu will conduct an assessment with military and security officials, his office said.
The massive rocket attack came amid tensions following rocket attacks from the Gaza Strip, clashes at the Al-Aqsa mosque compound and the launch of an Iranian drone from Syria earlier in the week.
Following these incidents, Hezbollah reaffirmed its willingness to enter the conflict.
While it is possible that the rocket fire from Lebanon was carried out by Palestinian groups based there, it is unlikely that they did so without the dispassionate approval of the group that controls southern Lebanon.
"Hezbollah categorically condemns the attack by the Israeli occupation forces on Al-Aqsa Mosque and their attacks on the worshipers," Hezbollah said in a statement.
"Hezbollah expresses its full solidarity with the Palestinian people and resistance groups and pledges to stand by them in all measures they take to protect the faithful, the Al-Aqsa Mosque and prevent the enemy from continuing its attacks." the organization announced.
At this time, it is known that in response to the bombings, Israel carried out airstrikes on Lebanese soil.
Defense Minister Yoav Gallant visited an Iron Dome missile array in southern Israel, where he was briefed on recent events on the Gaza front.
Gallant issued a stark warning, saying that Israel "will cripple anyone who tries to harm us" and that enemies will regret taking action against Israel.
Meanwhile, Hamas leader I. Haniyeh landed in Lebanon a while ago for meetings in Beirut.
The Hamas leader is expected to coordinate the group's actions and policies with Hezbollah.
Tensions in the region are high as the risk of a violent eruption on multiple fronts rises.
Israel's defense minister ordered the army to be on alert at all of Israel's borders to respond to potential attacks.
Behind it all is Erdogan attacking Netanyahu through Hezbollah and Hamas
Turkish President Recep Tayyip Erdogan on Wednesday condemned an Israeli police raid on Jerusalem's Al-Aqsa mosque that led to clashes with worshippers, calling such actions at the mosque a "red line" for Turkey.
"I condemn the heinous acts against the first qiblah of Muslims in the name of my country and people and call for the attacks to stop as soon as possible," Erdogan said in a speech during the fast.
"This is a policy of repression, a policy of blood, and a policy of provocation. Turkey can never remain silent and unmoved in the face of these attacks," Erdogan stressed.
"Setting foot in the Al-Aqsa Mosque and desecrating the sanctity of the Haram al-Sharif is a red line for us," he said.
Erdogan's comments come despite Israel and Turkey formally announcing last August that they would normalize relations by returning ambassadors and consuls, after years of tensions.
