Ebrahim Raisi, the Iranian President known for his hard-line stance and close ties to the country's supreme leader, passed away at the age of 63.
Raisi played a significant role in the mass executions of thousands in 1988 and later presided over Iran as it pursued uranium enrichment to near weapons-grade levels and carried out a substantial drone-and-missile attack on Israel.
President Raisi was travelling back to Iran following a visit to Azerbaijan when his helicopter came down.
