Following the confirmed deaths of Iran's Supreme Leader and Supreme National Security Council Secretary Ali Larijani in Israeli airstrikes, newly titled Leader Mojtaba Khamenei appointed Saeed Jalili to head the national security council and nuclear negotiations. The military exchange intensified as US CENTCOM deployed 5,000-pound bunker-busters against fortified Iranian anti-ship missile sites near the Strait of Hormuz and a US-Israeli strike in Dorud reportedly killed seven civilians, while another projectile struck the Bushehr nuclear power plant compound. In direct retaliation, Iran launched massive ballistic missile and drone barrages causing power outages in Tel Aviv and triggering air defenses over Jerusalem, Riyadh, and the UAE, alongside strikes on US positions in Iraq and Saudi Arabia. Domestically, Iranian authorities executed Kourosh Keyvani for allegedly spying for Israel and violently dispersed Chaharshanbe Suri celebrations in Tehran, even as domestic militants attacked a courthouse and Friday Imam's office in Larestan. Internationally, the escalating conflict prompted Saudi Arabia to host an emergency foreign ministers' summit, forced the USS Gerald R. Ford to divert to Greece after an onboard fire, and led Ukrainian President Volodymyr Zelensky to publicly warn that the US has abandoned Ukraine to focus on the Middle East.
