Iran's Supreme Leader Mojtaba Khamenei says murderers will pay

The killing of Ali Larijani shows how important he was and how great the "hatred of the enemies of Islam toward him" was. That message was published on Mojtaba Khamenei's social media account.

Mojtaba Khamenei promises revenge for "every drop of blood" and that "the murderers must pay."

Mojtaba Khamenei was appointed to succeed his father as Iran's supreme leader on March 8. However, he has not been seen or heard from since the US and Israel launched their attacks on Iran on February 28.

The statements that have since been reported to have come from him have been in writing.
