Iran's president, seven others, have died in a helicopter crash: here's what we know — and what we don't

Iran's President Ebrahim Raisi, 63, has died after his helicopter crashed in a remote area of the country on Sunday, the Iranian government confirmed Monday. In a country with a cleric-led government where the supreme leader has the final say, Raisi wasn't the highest ranked official, but the highest elected official.

Raisi was a conservative hardliner elected in 2021 and was viewed as a protege of Supreme Leader Ayatollah Ali Khamenei. Raisi's government faced mass protests over the suffering economy and women's rights. Relations between Iran and the West have also worsened during his tenure, with the country accelerating its nuclear enrichment program to weapons-grade levels.

Raisi's death comes at a time when turmoil is roiling the Middle East amid the Israel-Hamas war. The Iran-backed militant group Hamas ignited the current conflict in its deadly Oct. 7 attack on Israel. And just weeks ago, Iran launched a direct attack against Israel in a drone and missile attack in response to Israel's deadly strike on a diplomatic compound in Damascus, Syria.
