Israel announced dozens of new air strikes on Hezbollah strongholds in Lebanon Tuesday, a day after 492 people, including 35 children, were killed in the deadliest bombardment since a devastating war in 2006.

Israel’s overnight strikes on southern Lebanon came after it said it had killed a “large number” of militants when it hit about 1,600 suspected Hezbollah targets around the country.

Hezbollah said Tuesday it had launched volleys of missiles at Israeli military bases, hours after 180 of its projectiles and an unmanned aerial vehicle crossed into Israeli airspace, sending people in the city of Haifa running for shelter.

The Israeli military said more than 50 projectiles were fired into northern Israel in less than 10 minutes on Tuesday morning, most of which were intercepted.

In Lebanon, Monday’s raids killed 492 people, including 35 children and 58 women, and wounded 1,645, according to the health ministry, which said “thousands of families” had fled their homes.

“Everyone is heading (to Lebanese capital Beirut) with their children and their belongings — it’s the first time we see such panic since 2006,” said Lebanese journalist Nazir Reda, who was driving to his hometown near the Israeli border to get his family away from the violence.

Longtime foes Hezbollah and Israel have been locked in near-daily cross-border exchanges of fire for nearly a year, since Palestinian militant group
Hamas staged an unprecedented attack on Israel on October 7.

Hezbollah, which has been fighting Israel for decades, and other Iran-backed militants in the region have been drawn into the violence.

Monday’s bombardment of Lebanon was by far the largest, not just in the past year, but since the Israel-Hezbollah war in the summer of 2006.

That war killed 1,200 people in Lebanon, mostly civilians, and 160 Israelis, most of them soldiers, and devastated large swathes of Hezbollah’s strongholds.

– ‘Operation Northern Arrows’ –

Israel has dubbed its large-scale raids on Hezbollah “Operation Northern Arrows” after announcing earlier this month it was shifting the focus of its firepower from Gaza to Lebanon.

World leaders have expressed alarm over the rapid escalation on the Lebanon front, with UN chief Antonio Guterres’s spokesman saying he was “gravely alarmed” and the EU’s top diplomat Josep Borrell warning “we are almost in a full-fledged war”.

France and Egypt called on the United Nations Security Council to intervene, while Iraq requested an urgent meeting of Arab states on the sidelines of the UN General Assembly in New York.

The Pentagon said it was sending a small number of additional US military personnel to the Middle East after thousands were deployed earlier alongside warships, fighter jets and air defence systems.

A US official, speaking on condition of anonymity at the assembly, said that Washington opposed an Israeli ground invasion targeting Hezbollah and had “concrete ideas” on how to de-escalate the crisis.

G7 foreign ministers said in a joint statement that “no country stands to gain” from escalating conflict, warning of “unimaginable consequences” if a regional war broke out.

– ‘Most difficult week for Hezbollah’ –

Israeli army chief Herzi Halevi said Monday’s strikes hit combat infrastructure Hezbollah had been building for two decades, while
Defence Minister Yoav Gallant called Monday “a significant peak” in the operation.

“This is the most difficult week for Hezbollah since its establishment –- the results speak for themselves,” he said.

“Entire units were taken out of battle as a result of the activities conducted at the beginning of the week in which numerous terrorists were injured.”

Prime Minister Benjamin Netanyahu said Israel was acting to change the “security balance” in the north, wile Hezbollah said it was in a “new phase” of confrontation with Israel.
