Iran’s Supreme Leader Ayatollah Ali Khamenei said Tuesday that the Iranians will attack to defend themselves if they are threatened by either the United States or Israel.

Speaking in a live television address, Khamenei said that Iran would retaliate “on the same level” of any U.S. or Israeli attack.
