Hezbollah leader Hassan Nasrallah has been killed after airstrikes in Beirut, the Israeli army has said.

Recent weeks have seen Israel unleash a barrage of strikes against Lebanon after it turned its attention to the conflict at its northern border.

On Friday, Israel targeted the capital Beirut with a series of attacks claiming to have struck the headquarters of Hezbollah.

The Israel Defence Forces (IDF) said it carried out a “precise strike” on Hezbollah’s “central headquarters”, which it claimed was “embedded under residential buildings in the heart of the Dahieh in Beirut”.

The first wave of attacks shook windows across the city and sent thick clouds of smoke billowing into the air.

While Israel stressed it had been a “precise” strike, preliminary figures from Lebanon’s health ministry confirmed at least six other people were killed and 91 were wounded.

Israel said Nasrallah was the intended target and initially there were claims he had survived.

However, after several hours of confusion, his death was confirmed by Israel.

“Hassan Nasrallah will no longer be able to terrorise the world,” the IDF said.

Hours later, a defiant Hezbollah confirmed Nasrallah’s death but vowed their fight with Israel would continue after confirming they had fired upon sites in northern Israel.

“The leadership of Hezbollah pledges to the highest, holiest, and most precious martyr in our path full of sacrifices and martyrs to continue its jihad in confronting the enemy, supporting Gaza and Palestine, and defending Lebanon and its steadfast and honourable people,” they said.

Alongside claiming to have killed Nasrallah, the IDF said it had killed a number of other commanders, including Ali Karaki, the commander of the southern front.

The country’s military said the strike was carried out while Hezbollah leadership met at their underground headquarters in Dahieh.

In the aftermath of the most recent attacks, an Israeli military spokesperson declined to comment on whether US-made Mark 84 heavy bombs were used in the strike against Nasrallah.

“The strike was conducted while Hezbollah’s senior chain of command were operating from the headquarters and advancing terrorist activities against the citizens of the State of Israel,” Lieutenant Colonel Nadav Shoshani said in a media briefing.

He continued: “We hope this will change Hezbollah’s actions.”

He added the number of civilian casualties was unclear but blamed Hezbollah for positioning itself in residential areas.

“We’ve seen Hezbollah carry out attacks against us for a year. It’s safe to assume that they are going to continue carrying out their attacks against us or try to,” he said.

Meanwhile, Iran said it was in constant contact with Hezbollah and other allies to determine its “next step”, but Reuters reported the country’s supreme leader was transferred to a secure location in light of the latest attack.

Speaking after the attack, Ayatollah Ali Khamenei called on Muslims “to stand by the people of Lebanon and the proud Hezbollah” and said: “The fate of this region will be determined by the forces of resistance, with Hezbollah at the forefront,” state media reported.

Nasrallah’s death will be a blow to Hezbollah as it continues to reel from a campaign of escalating Israeli attacks.

Nasrallah is latest Hezbollah leader to fall

While Nasrallah’s death is certainly the most high-profile of recent attacks, it continues a trend of Israel targeting Hezbollah’s leadership structure.

Also on Saturday, in the early hours of the morning, the commander of the group’s missile unit and his deputy were killed in another Israeli attack in southern Lebanon.

Then, in a separate strike overnight on Friday, the IDF said it killed the head of Hamas’s network in southern Syria.

This followed the deaths of other senior commanders, including Muhammad Qabisi, earlier in the month.

The leader of Hezbollah is dead.

This is a very big moment, not just in this conflict but for the future of the Middle East.

In 2006, the last Lebanon War, Israel tried and failed to kill him.

Last night, in a huge series of strikes on southern Beirut, they finally hit their target.

Listen: What is Hezbollah and how powerful is it?

Over the past 18 years Nasrallah has grown Hezbollah in his image, expanding its forces, building its infrastructure and significantly expanding its arsenal.

He wasn’t just the leader of Hezbollah, he was a global figurehead of anti-Israel resistance.

With Iran’s help, Hezbollah became one of the best armed non-state militaries in the world.

It is now decapitated and in disarray.

During the past decades Israel has also been at work, steadily gathering intelligence on Nasrallah and Hezbollah, building a vast database of information, an effort which arguably distracted them from better understanding the intentions of Hamas.

The intelligence successes of the past days have helped restore Israel’s reputation after the stunning failures on October 7.

Iran and Hezbollah must choose

This is a pivotal moment.

Iran and Hezbollah must now decide how to respond: fight, or backdown.

The strike also killed Ali Karaqi, commander of Hezbollah’s southern front and labelled as the second most wanted by the IDF.

It is still unclear who else died in the strike, but given the location and the presence of top officials, it seems likely that other senior figures would have been eliminated too.

Nasrallah will be replaced.

The assassination of enemy leaders can prove to be a short-term victory because they are often succeeded by someone more formidable than before, as witnessed by the killing of the former Hezbollah leader Abbas al Moussawi in 1992.

He was succeeded by Nasrallah.

The working assumption is that the group will respond with barrages of missiles into Israel, probably targeting Tel Aviv.

But Hezbollah’s command structure has been severely degraded by Israel.

Nasrallah had become isolated as the IDF had steadily killed commanders over a fortnight of scything airstrikes on their compounds in Beirut and elsewhere.

It will probably take time to co-ordinate a response and it will probably be done with Iranian guidance.

Nasrallah might be dead, but Hezbollah isn’t

Hezbollah is badly wounded, not just as a paramilitary force but in the eyes of the Lebanese people, many of whom are angry their country is now facing another period of devastating violence.

This might be a moment for more moderate voices within Lebanon, including the national armed forces, to step in.

As the war escalated over recent weeks, noticeable divisions emerged between Tehran and Nasrallah.

He remained an important ally, however, a trusted advisor to Iran’s Supreme Leader, and this will come as a personal blow to him.

Having resisted the opportunity to get involved so far, Iran might decide the time has come to take the gloves off and deploy what is left of the thousands of missiles they’ve provided Hezbollah with.

Alternatively, after such a difficult ten days, Tehran might conclude that this round of fighting needs to end and pull back with its main proxy still in some shape to rebuild and fight another day.

With such momentum behind Israel, Iran will also be concerned about its own fate and that of its smaller proxies in Iraq and Syria.

Ultimately, the reason for Hezbollah’s existence – to act as insurance against an Israeli attack on Iran’s nuclear facilities – hasn’t changed, but if Tehran calculates its proxies can no longer act as that shield it might try to accelerate its nuclear programme.

Could a ground invasion follow?

The Israeli government has choices of its own: order a ground invasion of southern Lebanon or continue with an air campaign that has delivered such dramatic successes.

There will be strong and compelling voices in Netanyahu’s cabinet urging him to take advantage of the situation and send troops in, but Hezbollah is not defeated, thousands of its soldiers remain and they are likely hiding in the vast tunnel network under the hills across the border.

Even a limited ground invasion risks large loss of life, on both sides, and the potential Israel will be lured into something more prolonged than it intended.

Nasrallah’s death might change the dynamic in Gaza too.

Yahya Sinwar, the leader of Hamas, has clung on and rejected ceasefire attempts in the hope that Hezbollah and Iran would go to war with Israel, dragging its enemy into a multi-front and unwinnable conflict.

That might still happen, but just as Nasrallah became isolated, so too is Sinwar.

The much trumpeted “unity of arenas” has failed to join up.

The Middle East might often look chaotic to outsiders, but there are unspoken rules generally acknowledged and followed by belligerents.

For years Hezbollah and Israel acted within the unwritten but understood parameters of a shadow war.

Then, eleven months ago on 8 October, Hezbollah attacked Israel out of solidarity with Hamas.

Nasrallah tied Lebanon’s fate to Hamas, insisting that Hezbollah would only stop when the fighting ended in Gaza.

That ceasefire never came.

The rules shifted as the crossfire escalated, but it remained broadly contained within boundaries understood by both sides.

Until two weeks ago, 17 September, when thousands of pagers started exploding across Beirut and Lebanon.

It is possible Nasrallah had concluded that Israel was war-weary, and he overestimated the domestic and international pressure Netanyahu was under to end the fighting.

He might have believed that Netanyahu had neither the will nor the support to open up another front.

He, like so many of us, maybe assumed US influence on Israel would prevail.

Those miscalculations cost him his life.

At least 43 people have been killed across four states after Hurricane Helene barrelled its way across southeastern US.

Emergency crews are racing to rescue people trapped in flooded homes after Helene struck the coast of Florida as a highly destructive Category 4 storm.

It generated a massive storm surge, wreaking a trail of destruction extending hundreds of miles north.

Millions are without power in Florida and neighbouring states.

Meanwhile, dozens of patients and staff have been rescued from the roof of a flooded Tennessee hospital following a “dangerous rescue operation”.

Tennessee Senator Bill Hagerty said more than 50 people are now safe after becoming stranded on the Unicoi County Hospital.

The hospital was engulfed in “extremely dangerous and rapidly moving water”, according to Tennessee’s Ballad Health, making a boat rescue too treacherous.

A police helicopter was ultimately able to land on the roof after other helicopters failed to reach the hospital due to the storm’s winds.

Local official Michael Baker told Sky News the flooding was “unprecedented”.

“We’ve never seen anything like this,” he said.

As of early afternoon, Helene, which has been downgraded to a tropical depression, was packing maximum sustained winds of 35 mph (55 kph) as it slowed over Tennessee and Kentucky, the National Hurricane Center said.

It struck overnight with maximum sustained winds of 140 mph (225 kph) in the rural Big Bend area, the northwestern part of Florida.

The National Hurricane Center said preliminary information shows water levels reached more than 15ft above ground in that region.

US President Joe Biden has approved emergency declaration requests from the governors of several southern states affected by Helene.

Georgia, Florida, Alabama, North Carolina and South Carolina are being supported by emergency response personnel including search and rescue teams, medical support staff and engineering experts.

Georgia Governor Brian Kemp has said dozens of people are trapped in buildings damaged by the storm, with multiple hospitals in southern Georgia without power.

In western North Carolina, Rutherford County emergency officials have told residents near the Lake Lure Dam to immediately evacuate to higher ground, warning “Dam failure imminent”.

Meanwhile, Florida Governor Ron DeSantis said the damage from Helene in the area appears to be greater than the combined damage of Idalia and Hurricane Debby in August. “It’s demoralizing,” he said.

Many stranded in places like Tampa could only be reached by boat, with officials warning the water could contain live wires, sewage, sharp objects and other debris.

More than four million properties are without power across Florida, Georgia, the Carolinas, Virginia, Kentucky, Tennessee and Ohio, according to the logging website, PowerOutage.

Why this hurricane season is defying forecasts

Despite Helene’s power, this hurricane season has been more remarkable for its lack of activity.

At the start of the hurricane season, which runs from 1 June to 30 November, sea surface temperatures were (and remain) off-the-charts warm.

It’s this ocean heat that fuels tropical storms.

This combined with a developing La Nina phenomenon led the US forecasters to predict 2024 would be a major hurricane season. Between 17 and 24 storms were expected, with eight to 13 developing into hurricanes.

Hurricane Beryl grazed the coast of Jamaica in July as a Category 5 hurricane. It was the earliest storm of that size ever recorded and was seen as a harbinger of the prediction. But, so far at least, it’s failed to materialise.

There have been just six hurricanes so far this year – slightly below average. But why?

It seems to be due to what’s happening on the other side of the Atlantic where ocean warming forced the African monsoon further north than usual.

This led to catastrophic flooding in central and west Africa displacing millions, but it also shifted the weather system that usually spawns hurricanes and spins them across the Atlantic.

There’s already abundant evidence our warming oceans and atmosphere are making storms more intense – but predicting where they will occur and how often is never simple – and perhaps getting even harder as our planet gets hotter.

Prior to the hurricane making landfall, officials in Florida begged residents to evacuate. The sheriff’s office in rural Taylor County issued a chilling warning to those who refused to leave.

“Please write your name, birthday, and important information on your arm or leg in a permanent marker so that you can be identified and family notified,” the post on Facebook said.

Forecasters now expect the storm to continue weakening across Tennessee and Kentucky.

It is feared heavy rain over the Appalachian Mountains could cause mudslides and flash flooding.
