Everything you need to know about Ayatollah Ali Khamenei, supreme leader of Iran

A week after Israel launched a surprise attack on Iran aiming to wipe out its nuclear program, all eyes are now on the country’s reclusive supreme leader, Ayatollah Ali Khamenei.

On Thursday, following an Iranian missile strike that hit an Israeli hospital, Israel Defense Minister Israel Katz said in a statement that "Khamenei will be held accountable for his crimes," adding during a visit to one of the impact sites that "a person like that should not exist," later calling him "the modern day Hitler," according to the Times of Israel.
