Hezbollah leader Sayyed Hassan Nasrallah, whose death was announced on Saturday, led the Lebanese group through decades of conflict with Israel, overseeing its transformation into a military force with regional sway and becoming one of the most prominent Arab figures in generations — with Iranian backing.

Hezbollah said in a statement that Nasrallah had been killed, but it did not say how. The Israeli military said earlier it had killed Nasrallah in an airstrike on the group’s central headquarters in the southern suburbs of Beirut on Friday.

Nasrallah’s death deals a huge blow to the group. He will be remembered among his supporters for standing up to Israel and defying the US. To enemies, he was head of a terrorist organisation and a proxy for Iran’s Shia Islamist theocracy in its tussle for influence in West Asia.

His regional influence was on display over nearly a year of conflict ignited by the Gaza war, as Hezbollah entered the fray by firing on Israel from southern Lebanon in support of its Palestinian ally Hamas, and Yemeni and Iraqi groups followed suit, operating under the umbrella of “The Axis of Resistance”. “We are facing a great battle,” Nasrallah said in an August 1 speech at the funeral of Hezbollah’s top military commander, Fuad Shukr, who was killed in an Israeli strike on the Hezbollah-controlled southern suburbs of Beirut. Yet when thousands of Hezbollah members were injured and dozens killed, when their communications devices exploded in an apparent Israeli attack last week, that battle began to turn against his group.

Responding to the attacks on Hezbollah’s communications network in a Sept. 19 speech, Nasrallah vowed to punish Israel.

“This is a reckoning that will come, its nature, its size, how and where? This is certainly what we will keep to ourselves and in the narrowest circle even within ourselves,” he said.

He had not given a broadcast address since then.

Israel has meanwhile dramatically escalated its attacks, killing several senior Hezbollah commanders in targeted strikes and unleashing a massive bombardment in Hezbollah-controlled areas of Lebanon, which has killed hundreds of people. Recognised even by his enemies as a skilled orator, Nasrallah’s speeches were followed by friend and foe alike. Wearing the black turban of a sayyed, or a descendent of the Prophet Mohammad, Nasrallah used his addresses to rally Hezbollah’s base but also to deliver carefully calibrated threats, often wagging his finger as he does so.

He became secretary general of Hezbollah in 1992 aged just 35, the public face of a once shadowy group founded by Iran’s Revolutionary Guards in 1982 to fight Israeli occupation forces.

Israel killed his predecessor, Sayyed Abbas al-Musawi, in a helicopter attack. Nasrallah led Hezbollah when its guerrillas finally drove Israeli forces from southern Lebanon in 2000, ending an 18-year occupation.

‘Divine victory’

Conflict with Israel largely defined his leadership. He declared “Divine Victory” in 2006 after Hezbollah waged 34 days of war with Israel, winning the respect of many ordinary Arabs who had grown up watching Israel defeat their armies.

But he became an increasingly divisive figure in Lebanon and the wider Arab world as Hezbollah’s area of operations widened to Syria and beyond, reflecting an intensifying conflict between Shia Iran and US-allied Sunni Arab monarchies in the Gulf.

While Nasrallah painted Hezbollah’s engagement in Syria — where it fought in support of President Bashar al-Assad during the civil war — as a campaign against jihadists, critics accused the group of becoming part of a regional sectarian conflict.

At home, Nasrallah’s critics said Hezbollah’s regional adventurism imposed anunbearable price on Lebanon, leading once friendly Gulf Arabs to shun the country — a factor that contributed to its 2019 financial collapse.

In the years following the 2006 war, Nasrallah walked a tightrope over a new conflict with Israel, hoarding Iranian rockets in a carefully measured contest of threat and counter threat.

The Gaza war, ignited by the October 7 Hamas attack on Israel, prompted Hezbollah’s worst conflict with Israel since 2006, costing the group hundreds of its fighters including top commanders.

After years of entanglements elsewhere, the conflict put renewed focus on Hezbollah’s historic struggle with Israel.

“We are here paying the price for our front of support for Gaza, and for the Palestinian people, and our adoption of the Palestinian cause,” Nasrallah said in the August 1 speech.

Nasrallah grew up in Beirut’s impoverished Karantina district. His family hail from Bazouriyeh, a village in the Lebanon’s predominantly Shi’ite south which today forms Hezbollah’s political heartland.

He was part of a generation of young Lebanese Shias whose political outlook was shaped by Iran’s 1979 Islamic Revolution.

Before leading the group, he used to spend nights with frontline guerrillas fighting Israel’s occupying army.

His teenage son, Hadi, died in battle in 1997, a loss that gave him legitimacy among his core Shia constituency in Lebanon.

Powerful enemies

He had a track record of threatening powerful enemies.

As regional tensions escalated after the eruption of the Gaza war, Nasrallah issued a thinly veiled warning to US warships in the Mediterranean, telling them: “We have prepared for the fleets with which you threaten us.”

In 2020, Nasrallah vowed that US soldiers would leave the region in coffins after Iranian general Qassem Soleimani was killed in a US drone strike in Iraq.

He expressed fierce opposition to Saudi Arabia over its armed intervention in Yemen, where, with US and other allied support, Riyadh sought to roll back the Iran-aligned Houthis.
