Event Summary

Iran's Supreme Leader Ali Khamenei was killed in joint US-Israeli strikes on February 28.

The United States and Israel have been implicated in the strikes, with leaders like Donald Trump and Benjamin Netanyahu commenting on the event, suggesting it offers a chance for change in Iran.
