Israel struck multiple targets in Lebanon on Sunday, pressing Iran-backed Hezbollah with more attacks after it struck a huge blow by killing the group’s leader Sayyed Hassan Nasrallah.

The Israeli military said the air force had “struck dozens of Hezbollah terror targets in Lebanon, including launchers that were aimed toward Israeli territory, structures in which weapons were stored and additional Hezbollah terrorist infrastructure”.

The navy had intercepted a projectile approaching Israel from the area of the Red Sea and another eight projectiles coming from Lebanon had fallen in open areas, it said in a statement.

Nasrallah was killed in a massive Israeli air attack on Friday on the group’s headquarters in Beirut’s southern suburbs. It was a major blow to Hezbollah and to Iran, removing an influential ally who helped build Hezbollah into the linchpin of Tehran’s network of allied groups in the Arab world.

Israel announced his killing on Saturday and Hezbollah later confirmed his death.

In its announcement, Hezbollah said it would keep fighting Israel and has continued to fire rockets at it, including a salvo on Sunday morning.

Nasrallah’s death capped a traumatic fortnight for Hezbollah, starting with the detonation of thousands of communications devices used by its members.

Israel was widely assumed to have carried out that action but has not confirmed or denied it did.

The escalation has increased fears the conflict could spin out of control, potentially drawing in Iran as well as the United States, Israel’s closest ally.

Hezbollah and Israel have been fighting in parallel with Israel’s war in Gaza against Hamas since the Iran-backed Palestinian group’s attack on Israel last Oct. 7.

Lebanon’s health ministry said 33 people had been killed in Israeli strikes on Lebanon during Saturday, bringing the total toll since hostilities broke out on Oct. 8 last year to more than 1,670, including 104 children.

In Beirut, displaced families spent the night on the benches at Zaitunay Bay, a string of restaurants and cafes on Beirut’s waterfront where private security usually shoos away any loiterers.

On Sunday morning, families with nothing more than a duffle bag of clothes had rolled out mats to sleep on and poured tea for themselves.

“You won’t be able to destroy us, whatever you do, however much you bomb, however much you displace people – we will stay here. We won’t leave. This is our country and we’re staying,” said Francoise Azori, a Beirut resident jogging through the area.

The United Nations’ World Food Programme said in a statement on Sunday it had launched an emergency operation to provide food for up to 1 million people affected by the conflict in Lebanon.
