Ali Larijani

Ali Larijani was killed on 16 March 2026 in an Israeli overnight strike on Tehran, the most senior Iranian official to die since Supreme Leader Ali Khamenei on 28 February. His death removed both the institutional memory of Iran's prior negotiations and its most credible diplomatic operator, closing the last plausible route for a back-channel settlement at the moment Iran needed it most. Three days before his killing, Larijani had been standing with Masoud Pezeshkian at the al-Quds Day rally when an explosion struck Ferdowsi Square.

Born in 1958 in Najaf, Iraq, into a clerical family, Larijani trained as a mathematician before serving as an IRGC officer and entering politics. He chaired the Islamic Consultative Assembly from 2008 to 2020, the longest tenure of any speaker in the Islamic Republic, and led Iran's nuclear negotiating team from 2005 to 2007. His brothers held simultaneous positions across the Islamic Republic's institutions for two decades: Sadegh as former judiciary chief, Mohammad Javad as human rights spokesman, and Fazel as cleric and former MP. He was appointed SNSC secretary in 2024, though formal ratification had not occurred before his death. In his last weeks he publicly declared Iran would not negotiate with the United States, the first named official to contradict Trump's claims of Iranian diplomatic openings.

Larijani's killing degraded the principlist network he anchored. The vacancy accelerated the IRGC military council's capture of Iranian state authority, filling the decision-making gap the civilian principlist bloc once occupied. His removal alongside intelligence chief Khatib and three IRGC commanders within 48 hours reflected Israel's deliberate targeting of Iran's political tier alongside its military capacity. Three months on, as Iran and the United States signed the June 2026 Islamabad memorandum, the Majlis hardliner bloc that challenged Ghalibaf's signature cited his absence: with Larijani gone, there was no senior principlist with both the authority and the credibility to negotiate a face-saving formula on Iran's behalf.
