In a statement released just moments ago, Hezbollah says its leader Hassan Nasrallah is dead.
Earlier, the Israeli military said it had killed the Iran-backed group's leader in Friday's strike on Beirut.
"His Eminence, the Master of Resistance, the righteous servant, has passed away to be with his Lord," the Hezbollah statement reads.
The group seemed to confirm that he had died in air strikes on Beirut, saying his death had come "following the treacherous Zionist raid on the southern suburb.".
The group also went on to "pledge" its fight against Israel and continued support of "Gaza and Palestine, and defending Lebanon and its steadfast and honourable people."
Eight key things to know as Hezbollah confirms Nasrallah's death
- A series of air strikes were carried out by Israel on Beirut on Friday - these were accompanied by reports that Nasrallah was a target
- Israeli air strikes on Lebanon continued into this morning, as our correspondent in Beirut described seeing smoke rising over the capital's southern suburbs
- Hezbollah has also reported firing rockets into Israel today - with the IDF acknowledging having identified and intercepted some
- Meanwhile, we heard this morning about people being displaced overnight from the southern suburbs of Beirut and sleeping on streets or in their cars
- At around 09:00 BST the IDF said they had killed Nasrallah, along with other senior members of Hezbollah, in a strike on the group's central headquarters in Dahieh
- The Iranian-backed group has since confirmed Nasrallah has been killed
- A Hezbollah statement describes Nasrallah as a martyr, and says the group would continue its fight against Israel
- Separately, Lebanon's transport ministry told an Iranian aircraft not to enter Israel's airspace, while the EU has said airlines should avoid Lebanese and Israeli airspace for the next month.
In Israel, Nasrallah's death will be viewed as a huge victory
In Israel, the killing of Hasan Nasrallah will be seen as a huge victory.
For more than 30 years he has been the beating heart of Hezbollah. With the aid of his close allies in Iran, he turned Hezbollah into a fighting force that in 2000 forced Israel to end a two-decade occupation of south Lebanon.
In 2006, he led Hezbollah as it fought Israel to a standstill.
Nasrallah has been Israel’s biggest single enemy – in recent years, only Yahya Sinwar, mastermind of the Hamas attack on Israel in October last year, has come close.
Against the wishes of its American allies, Israel has taken the fight to Hezbollah after almost a year of an attritional border war.
In the last few weeks Israel has activated a war plan it has been working on since the last war with Hezbollah ended in 2006.
Israel has inflicted huge damage on its enemy in Lebanon. Killing its leader is the biggest blow of all.
The question now is how Hezbollah – and Iran – will respond. They might now be concluding that if they don’t hit back hard they will be facing a strategic defeat.
The uncertainty and danger in the Middle East is why the US and Israel’s western allies tried to persuade Prime Minister Benjamin Netanyahu to accept a ceasefire to create a pause for diplomacy.
Hamas stands in 'solidarity' with Hezbollah after Nasrallah's death
Palestinian militant group Hamas, who, alongside Lebanon-based Hezbollah is backed by Iran both militarily and financially.
In a statement from the Gaza-based group, it says it mourns the death of Hezbollah's leader and that it stands in "solidarity with the brothers in Hezbollah and the Islamic Resistance in Lebanon."
While the Israel-Hezbollah conflict has been going on for decades, the current war between them started after Hamas gunmen launched an attack from Gaza on 7 October, killing about 1,200 people.
Fighting between Hezbollah and Israel began escalating on 8 October 2023 - the day after the unprecedented attack.
Hezbollah fired at Israeli positions in solidarity with the Palestinians and says it will continue fighting Israel until a ceasefire in Gaza is met.
Iraq says Israel has crossed 'all red lines' in killing Hezbollah leader
The Houthi movement in Yemen has said it is mourning the death of the former Hezbollah leader - but has vowed that "support will grow stronger and bigger"
Iran's foreign ministry spokesman Nasser Kanaani said the strike was a "war crime" for which both Israel and the US should be held accountable, state media reported
The office of Iraq's prime minister has announced three days of mourning and said Israel has crossed "all red lines" through the killing of Nasrallah
