Ali Larijani: Iran Security Chief Reportedly Killed in Middle East Conflict

Israel’s claim of killing Ali Larijani, a pivotal figure in Iran’s security apparatus, marks a significant escalation in the ongoing conflict and raises questions about the future trajectory of Iran’s response. The reported strike, announced by Israeli Defence Minister Israel Katz on Tuesday, comes amid heightened tensions following joint US-Israeli strikes that killed Ayatollah Ali Khamenei in February. While Iranian authorities have yet to confirm Larijani’s death, his potential removal from the political landscape would represent a substantial blow to the Islamic Republic, particularly as he had emerged as a leading voice in the wake of the Supreme Leader’s assassination.

Larijani’s rise to prominence following Ayatollah Khamenei’s death was notable. Unlike his successor, Mojtaba Khamenei, who has remained largely out of public view since his appointment, Larijani actively engaged in public appearances, most recently at a pro-government rally in Tehran, signaling defiance against both Israel and the United States. This visibility underscored his increasingly influential role in navigating the complex geopolitical landscape and coordinating Iran’s response to the escalating conflict.

A Pragmatic Voice in Iran’s Hardline Establishment

Ali Larijani, born in Najaf, Iraq in 1957, was a veteran of Iran’s political system, representing a blend of ideological commitment and pragmatic statecraft. His lineage – the son of a prominent Shia cleric close to Ayatollah Ruhollah Khomeini, the founder of the Islamic Republic – provided him with deep roots within the country’s ruling elite. He earned a PhD in Western Philosophy from the University of Tehran, demonstrating an intellectual depth often absent in more purely religious figures.

Larijani’s career spanned multiple key positions. A veteran of the Islamic Revolutionary Guard Corps during the Iran-Iraq war, he later served as the head of state broadcasting, IRIB, for a decade beginning in 1994. He then transitioned to the legislature, serving as parliamentary speaker from 2008 to 2020. This diverse experience equipped him with a comprehensive understanding of Iran’s internal dynamics and its external relations.

In 2025, following the previous period of heightened conflict with Israel and the US, Larijani was reappointed as the head of Iran’s Supreme National Security Council (SNSC), a position he had previously held. The SNSC is the key body responsible for coordinating defense strategies and overseeing nuclear policy, making Larijani central to Iran’s security decision-making. His appointment signaled a shift towards a more pragmatic approach, recognizing his ability to balance ideological principles with the realities of international politics. As Ali Vaez of the International Crisis Group noted before the current war, Larijani was “a true insider, a canny operator, familiar with how the system operates.”

Navigating Nuclear Diplomacy and Regional Tensions

Larijani played a crucial role in Iran’s nuclear policy and diplomatic efforts. He actively engaged in negotiations with Gulf states, including Oman and Qatar, seeking to de-escalate regional tensions and cautiously explore avenues for nuclear talks. These efforts, however, were ultimately derailed by the outbreak of the current conflict. He consistently defended Iran’s right to uranium enrichment, framing it as a sovereign prerogative, while as well supporting the landmark 2015 nuclear deal – a position that put him at odds with hardliners who opposed any concessions to the West.

His involvement in the 2015 nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), highlights his willingness to engage in diplomacy, even with adversaries. The deal, which limited Iran’s nuclear program in exchange for sanctions relief, was hailed as a diplomatic breakthrough at the time. However, the withdrawal of the United States under President Donald Trump in 2018 led to the unraveling of the agreement and a renewed escalation of tensions. The Modern York Times provides detailed coverage of the JCPOA’s collapse and its consequences.

Larijani’s attempts to run for the presidency in 2005, 2021, and 2024 were unsuccessful, with his candidacy being disqualified on each occasion. This suggests a degree of resistance from within the Iranian establishment to his more pragmatic approach. Despite these setbacks, he remained a powerful figure, leveraging his position on the SNSC to shape Iran’s security policy.

The Shadow of Repression and Sanctions

In the years leading up to the current conflict, Larijani faced criticism for his role in the government’s response to widespread protests in Iran. The United States imposed sanctions on him in January, citing his involvement in the “violent repression of the Iranian people” following protests sparked by economic hardship. Rights groups documented thousands of deaths during the crackdown, accusing the government of using excessive force against peaceful demonstrators. Human Rights Watch has extensively documented the Iranian government’s human rights record, including its response to protests.

Larijani acknowledged the economic pressures contributing to the unrest but attributed the violence to foreign interference by the United States and Israel. This narrative reflects a common theme in Iranian political discourse, which often blames external actors for domestic challenges.

What Happens Next: A Succession Puzzle and Regional Ramifications

The confirmation of Ali Larijani’s death would create a significant power vacuum within Iran’s security establishment. While Mojtaba Khamenei has formally succeeded his father as Supreme Leader, his lack of public profile and experience raises questions about his ability to effectively lead the country during this critical juncture. Larijani’s absence could further empower hardliners within the regime, potentially leading to a more confrontational approach towards the West. The succession dynamics are further complicated by the fact that Larijani had cultivated relationships across various factions within the Iranian government, making his removal a destabilizing event.

The immediate impact of Larijani’s potential death will likely be felt in Iran’s ongoing negotiations with international powers. His pragmatic approach and diplomatic skills were seen as essential for navigating the complex challenges of the nuclear issue and regional tensions. Without his influence, the prospects for a negotiated settlement may diminish, increasing the risk of further escalation. The role of the International Atomic Energy Agency (IAEA) in verifying Iran’s nuclear activities will become even more critical in the absence of a trusted interlocutor like Larijani. The IAEA website provides detailed information on its verification activities in Iran.

Regionally, Larijani’s death could embolden Iran’s proxies in countries like Lebanon, Syria, and Yemen, potentially leading to an increase in attacks against US and Israeli interests. It could also prompt a reassessment of security strategies among Iran’s regional rivals, such as Saudi Arabia and the United Arab Emirates. The broader implications for regional stability are significant, and the international community will be closely monitoring the situation in the coming weeks and months.

For now, the situation remains fluid. Confirmation from Iranian authorities is pending, and the full extent of Larijani’s involvement in recent events remains unclear. However, the reported strike underscores the escalating risks in the Middle East and the potential for further conflict. The coming days will be crucial in determining whether the region can avert a wider war.
