19. Background
20. The war began on 28 February 2026, when the United States and Israel launched hundreds of air strikes against targets across Iran; one strike, on Supreme Leader Ali Khamenei's residential compound, killed him. On 1 March an Interim Leadership Council was established in Iran to exercise the functions of head of state after Khamenei's death. Iran blocked the Strait of Hormuz during the war and in late March 2026 declared sovereignty over it. Each side named its own campaign: the United States calls its initial air campaign Operation Epic Fury, Israel calls its campaign Operation Roaring Lion, and Iran calls its response Operation True Promise IV. American media have generally called the conflict the Iran war; some outlets called it the Third Gulf War, and Iranian state media called it the Third Imposed War.
21. Khamenei's death confirmed Reuters, 1 March 2026: Iranian state media confirm the supreme leader's death after first denying it, and Netanyahu says his compound was destroyed.

A two-week ceasefire between the United States, Israel and Iran, mediated by Pakistan, began on 8 April 2026, but the Islamabad Talks between the United States and Iran on 12 to 13 April ended without an agreement. On 17 June 2026 President Trump and Iranian President Pezeshkian signed a memorandum of understanding to end the war, and on 28 June the two countries agreed to stop exchanging attacks with each other.
