Overview On Wednesday, 18 March 2026 , Israel’s Defence Minister announced that the Israeli military had killed Iranian Intelligence Minister Esmail Khatib . The statement hinted at further “significant surprises” on all fronts, without providing details. Key Developments Israel confirms the elimination of Esmail Khatib , Iran’s top intelligence official. Earlier Israeli airstrikes killed senior Iranian security figures: Ali Larijani (security chief) and Gholamreza Soleimani , head of the Basij paramilitary force. Iran’s judiciary reported an “attack” in southern Iran, causing civilian and staff casualties at a site in Larestan County , Fars province. Iran announced state funerals for Larijani and Soleimani on the same day, emphasizing national mourning. Foreign Minister Abbas Araghchi stated that Larijani’s assassination would not destabilise Iran’s political system, even as the Revolutionary Guard vowed “definite revenge”. Important Facts The series of strikes marks an escalation in the covert conflict between Israel and Iran, targeting high‑level security officials. The killings of Larijani and Soleimani followed a pattern of Israeli operations aimed at curbing Iran’s regional influence. Iran’s retaliatory “attack” in the south, though not fully detailed, signals a possible shift from covert to overt actions within its own territory.
