On 27 September 2024, Hassan Nasrallah, the secretary-general of Hezbollah, was assassinated in an Israeli airstrike in Beirut. The strike took place while Hezbollah leaders were meeting at a headquarters located 60 feet (18 m) underground beneath residential buildings in Haret Hreik in the Dahieh suburb. Conducted by the Israeli Air Force using F-15I fighters, the operation involved dropping more than 80 bombs, destroying the underground headquarters as well as nearby buildings. The Israel Defense Forces (IDF) codenamed the operation "New Order" (Hebrew: סדר חדש, romanized: Seder Hadash).
On 28 September 2024, the IDF announced Nasrallah's death; his body was recovered from the rubble the next day. The attack resulted in at least 33 fatalities and more than 195 injuries, including civilians. The fatalities included: Ali Karaki, the commander of Hezbollah's Southern Front; other senior Hezbollah commanders; and Abbas Nilforoushan, deputy commander of the Islamic Revolutionary Guard Corps (IRGC) and commander of the Quds Force in Lebanon.
Earlier in September, some of Hezbollah's most severe setbacks occurred, including the 17 and 18 September explosions of its handheld communication devices and the 20 September assassination of Ibrahim Aqil, commander of the elite Redwan Force. Between 23 September, when Israel began its airstrikes on Lebanon, and 26 September, the day before the headquarters strike, Israeli attacks had killed over 700 people, injured more than 5,000, and displaced hundreds of thousands of Lebanese civilians. On 27 September, Israeli prime minister Benjamin Netanyahu addressed the United Nations (UN), saying Israel was dedicated to peace, but would continue to pursue its ongoing campaign against Hezbollah. The headquarters strike occurred after Netanyahu concluded his speech.
Lebanese prime minister Najib Mikati condemned this and prior Israeli attacks on Lebanon, denouncing the ongoing Israeli attacks as "a war of extermination". On 27 November, a ceasefire agreement between Israel and Lebanon went into effect, although several violations have since occurred.
Background
The day after Hamas's 7 October 2023 attacks on Israel, Hezbollah fired rockets at the Shebaa Farms, claiming solidarity with the "Palestinian people". This quickly escalated into regular cross-border military exchanges with Israel, impacting northern Israel, southern Lebanon and the Golan Heights. Hezbollah condemned the killing of civilians in Gaza, and said it aimed to pressure Israel by forcing it to fight on two fronts. Hezbollah offered an immediate ceasefire should a ceasefire also happen in Gaza. From 8 October 2023 to 20 September 2024, Hezbollah launched 1,900 cross border attacks, and Israel launched 8,300. The fighting killed 52 in Israel (including 27 civilians), 564 in Lebanon (including 133 civilians), and displaced entire communities in Israel and Lebanon, with significant damage to civilian infrastructure.
In July, another senior Hezbollah military leader, Fuad Shukr, was also assassinated in Beirut. On 10 September, the Israeli Defense Minister Yoav Gallant said Israel was shifting its focus from Gaza to the northern border.
On 17 and 18 September, thousands of handheld pagers and walkie-talkies exploded in a coordinated series of attacks. The explosions killed 42 people and injured at least 3,500, including many civilians. An unnamed Hezbollah official told Reuters 1,500 Hezbollah fighters were taken out of action by injuries. Despite Israel initially denying involvement with the attack, it was orchestrated by Israel's intelligence service (Mossad) and military.
In response, Hezbollah, who described the attack as a possible declaration of war by Israel, launched a rocket attack on northern Israel a few days later. On 20 September 2024, tensions further rose after Ibrahim Aqil was killed in an Israeli strike in Beirut, along with other senior commanders from the unit. After advising Lebanese citizens to evacuate, Israel began airstrikes on 23 September.
Since 23 September 2024, when Israel began its airstrikes on Lebanon, Israeli attacks have killed over 700 people, injured more than 5,000, and displaced hundreds of thousands of Lebanese civilians.
On 25 September, the United States and the European Union released a statement calling for a 21-day ceasefire. The statement was also signed by Australia, Canada, France, Germany, Italy, Japan, Saudi Arabia, the United Arab Emirates, the United Kingdom, and Qatar. US officials said that Netanyahu had agreed to this, but the next day Netanyahu denied any involvement in this plan, leaving US officials reportedly "furious". Netanyahu later backtracked, saying he shared the aims of the US proposal. According to Lebanese Foreign Minister Abdallah Bou Habib, Nasrallah had agreed to the temporary ceasefire days before the assassination.
Hassan Nasrallah
Hassan Nasrallah was a political leader in the Amal Movement, but left after the 1982 Israeli invasion of Lebanon began. He joined Hezbollah shortly after it was formed, and was elected the secretary-general of Hezbollah in 1992. He immediately set out to focus Hezbollah on fighting the Israeli occupation of southern Lebanon. He led Hezbollah to fight against the 1993 and 1996 Israeli military operations, and after the Qana massacre, his popularity skyrocketed in Lebanon. His time in command transformed Hezbollah into the world's most heavily armed non-state actor, with its paramilitary wing surpassing the Lebanese Army in strength. His speeches frequently included anti-Israeli and anti-Western sentiments. Nasrallah also closely aligned with Iran, and influenced Hezbollah in other significant ways throughout his tenure.
In the 1990s, Nasrallah was popular among Lebanese Shi'ites—and to a certain extent in the Arab and Muslim worlds—but he was much disliked by the Israeli and American governments. However, Hezbollah's role in ambushing an Israeli border patrol unit leading up to the 2006 Lebanon War was subject to local and regional criticism. During the Syrian civil war, Hezbollah fought on the side of Bashar al-Assad. While Hezbollah helped Assad stay in power, Hezbollah's popularity sharply declined given that Assad had become a pariah in the Arab world.
Under his leadership, Hezbollah faced criticism for its alleged involvement in the 2005 assassination of Lebanese PM Rafic Hariri and the 2020 Beirut port explosion. He has also consistently promoted the "Axis of Resistance," a network of Iran-supported militias focused on opposing Israel and the United States. Hezbollah's popularity surged again after the start of the Israel-Hezbollah hostilities in October 2023.
In October 1992, Israel tried to assassinate Nasrallah. In May 2004, Lebanese officials said they foiled an Israeli plot to kill Nasrallah. In the 2006 war, Israel dropped many bombs on buildings that may have housed Nasrallah.
A US official told ABC News that Nasrallah and several associates were in Beirut for a brief visit during the strike. According to The New York Times, Israeli leaders had tracked Hassan Nasrallah's location for months and opted to target him a week before the assassination, believing they had a limited timeframe before he moved elsewhere. Iranian officials told Reuters that after the pager attacks, Ali Khamenei sent Abbas Nilforoushan to Nasrallah, warning him that his life was in danger and asking him to flee to Iran; Nasrallah trusted his security and inner circle and refused.
Attack
In the early evening of 27 September 2024, the Israeli Air Force (IAF) conducted an airstrike on Hezbollah's central headquarters located in the Haret Hreik neighborhood, in the Dahieh suburb of Beirut. Media reports confirmed that Hezbollah leader Hassan Nasrallah was the target of the airstrike. Nasrallah and other senior Hezbollah leaders were meeting in a bunker more than 60 feet (18 m) underground. According to Le Parisien, citing a Lebanese security source, an Iranian mole was responsible for informing the IDF of Nasrallah's whereabouts before the strike occurred.
The strike was either conducted by the 119th "Bat" Squadron with F-16I Sufa jet-fighters or by the 69th Squadron with F-15I Ra'ams. Two officials said that over 80 bombs were dropped within minutes during the operation, though they did not specify the bombs' weight or type. Another official stated the munition was dropped within 10 seconds and were priced at 25 million Shekels.
The strike occurred shortly after Israeli Prime Minister Benjamin Netanyahu addressed the United Nations General Assembly to say that Israel's campaign against Hezbollah would continue. The Prime Minister's Office shared a photo that it says shows Netanyahu approving the airstrike. The image reportedly features Netanyahu in his New York hotel with his military secretary and chief of staff, prior to addressing the UN.
There was no immediate information on casualties in the strike. IDF spokesperson Rear Admiral Daniel Hagari stated Hezbollah's main headquarters were the target, located beneath residential buildings. Hezbollah's Al-Manar TV reported that four buildings were reduced to rubble as a result of the explosion, which was so powerful that tremors were felt up to 30 kilometres (19 mi) north of Beirut. Ambulances were seen heading to the scene, accompanied by wailing sirens. According to the National News Agency, the raids created a belt of fire that extended from the outskirts of Bourj el-Barajneh to Haret Hreik. Footage taken shortly after the explosion revealed a large crater.
Aftermath
Confirmation of Nasrallah's death
On 28 September 2024, Nasrallah's death was announced by the IDF. Hezbollah confirmed it later that day, ending the uncertainty over his condition. On 29 September 2024, Nasrallah's body was recovered with no obvious wounds; according to Reuters, two sources suggested he had died from blunt force trauma sustained during the attack.
Other casualties
The area struck by Israel is known to be densely populated. The impacted area consisted of civilian apartment buildings built over subterranean Hezbollah facilities; several structures were completely reduced to rubble and widespread destruction could be seen in the aftermath of the strike. The Lebanese health ministry reported at least 33 fatalities and 195 injuries as of 28 September, though most of the rubble has not been searched yet, and the number is almost certain to rise as dozens are missing.
Hezbollah also confirmed the death of Ali Karaki, commander of Hezbollah's Southern Front, along with other senior commanders. Abbas Nilforoushan, deputy commander of the Islamic Revolutionary Guard Corps (IRGC) and commander of the Quds Force in Lebanon, was also killed.
Succession
Immediately following the announcement of Nasrallah's death, Naim Qassem was named as the interim leader of Hezbollah. Three possible permanent successors were identified: Qassem; Ibrahim Amin al-Sayyed, head of the Political Council of Hezbollah; and Hashem Safieddine, Hezbollah's second in command, Nasrallah's cousin and also a cleric, who reportedly survived the attack on the Hezbollah headquarters.
On 29 September 2024, Al Arabiya reported that Safieddine had been named the new secretary-general of Hezbollah, which Hezbollah denied. Reuters reported that Hezbollah may have been reluctant to officially name a successor for fear he would be targeted by Israel for assassination. Four days later, Safieddine was assassinated during an Israeli airstrike in Beirut on 3 October, and Hezbollah confirmed his death on 23 October after his body was found. Qassem was then elected secretary-general of Hezbollah on 29 October 2024.
Funerals
The bodies of Nasrallah and Safieddine were secretly buried in temporary locations before their official funeral ceremonies, which were held on 23 February 2025.
Reactions
Domestic
Hezbollah and allies
Hezbollah said it would continue its fight against Israel. After the announcement of Nasrallah's death, the Hezbollah-affiliated Al-Manar TV aired Quran verses. Hezbollah supporters took to the streets mourning his death and gunfire was heard. On 30 September, Hezbollah's acting leader, Naim Qassem, said the group's struggle would continue, and that it was prepared to face an Israeli ground assault.
The Amal Movement, another Shia political group in Lebanon, said that the death of Nasrallah would not weaken the resistance. It called Nasrallah a "martyr" and pledged to remain "shoulder to shoulder, heart to heart, and arm to arm" against Israel. Hezbollah's Christian ally Michel Aoun gave condolences to Nasrallah's family, saying: "Lebanon has lost an exceptional leader who led the national resistance."
Lebanese government
Lebanese caretaker Prime Minister Najib Mikati denounced the attack, calling Lebanese civilians to "stand united in the face of aggression". He declared three days of mourning in Lebanon, beginning on 30 September, with flags to fly at half-staff on public buildings.
In Beirut, Lebanese army tanks were deployed near the Burj Al Ghazal bridge to prevent clashes between Shia and Christian neighborhoods. In the eastern part of the city, where Hezbollah's political rivals hold influence, some residents reacted to Nasrallah's death with a mix of surprise and celebration.
Iran
Following the strike on 27 September, The New York Times reported that Supreme Leader Ali Khamenei convened an emergency meeting of the Supreme National Security Council at his residence. Reuters reported that Khamenei had moved to a secure location in Iran under increased security measures and that authorities were investigating senior security officials and Revolutionary Guards officers, with some arrested as suspected Mossad spies.
