Israeli planes bomb southern Lebanon after radio blasts

Israel bombed southern Lebanon on Thursday and said it had thwarted an Iranian-led assassination plot, a day after explosions of Hezbollah radios that came on the heels of blasts in booby trapped pagers, setting the foes hurtling towards war.

The sophisticated attacks on armed group Hezbollah's communications equipment, which killed 37 people and wounded around 3,000 over two days, sowed disarray in Lebanon, with panicked residents abandoning their mobile phones.

"This isn't a small matter; it's war. Who can even secure their phone now? When I heard about what happened yesterday, I left my phone on my motorcycle and walked away," said Mustafa Sibal on a street near central Beirut.

A distant roar in the skies could be heard in Beirut from what Lebanese state media said was Israeli jets breaking the sound barrier – a sound that has grown increasingly common in recent months.

Israel said its warplanes struck villages in southern Lebanon overnight, and a security source and Hezbollah's al-Manar TV reported airstrikes near the border resumed on Thursday just after midday.

Hand-held radios used by Hezbollah detonated on Wednesday across Lebanon's south. The Lebanese health minister raised the death toll, saying 25 people had been killed and 608 injured in the country's deadliest day since cross-border fighting erupted between the militants and Israel in parallel with the Gaza war last year.

The previous day, hundreds of pagers – used by Hezbollah to evade mobile phone surveillance – exploded at once, killing 12 people, including two children, and injuring more than 2,300.

In a post on X, Lebanese Prime Minister Najib Mikati called on the United Nations Security Council to take a firm stand to stop Israel's "aggression" and "technological war" against his country.

Israel has not commented directly on the booby-trapped walkie-talkies and pagers, but multiple security sources have said the attacks were carried out by its spy agency Mossad.

Israel says its conflict with Hezbollah, like its war in Gaza against Palestinian armed group Hamas, is part of a wider regional confrontation with Iran, which supports both groups as well as armed movements in Syria, Yemen and Iraq.

On Thursday, Israeli security forces announced that an Israeli businessman had been arrested last month, accusing him of attending at least two meetings in Iran, where he allegedly discussed assassinating Prime Minister Benjamin Netanyahu, the defense minister or the head of the Shin Bet spy agency.

Last week, Shin Bet uncovered what it said was a plot by Hezbollah to assassinate former Defense Minister Moshe Ya'alon.

Israel has been accused of assassinations, including a blast in Tehran that killed the political head of Hamas and another in a Beirut suburb that killed a senior Hezbollah commander within hours of each other in July.

Despite the events of the past few days, a spokesperson for the UN peacekeeping mission in southern Lebanon said the situation along the frontier had "not changed much in terms of exchanges of fire between the parties."

"There was an intensification last week. This week it is more or less the same. There are still exchanges of fire. It is still worrying, still concerning, and the rhetoric is high," the spokesperson, Andrea Tenenti, told Reuters.

Israel and Hezbollah have been exchanging fire across the Israel-Lebanon border in parallel with the war Israel has waged in Gaza against Hamas, the Palestinian armed group whose fighters attacked Israel on October 7.

Tens of thousands of people have had to flee the Israel-Lebanon border area on both sides. Netanyahu vowed on Wednesday to return the evacuated Israelis "securely to their homes."
