A senior cleric in Iran has issued a fatwa declaring that anyone who threatens Iran’s Supreme Leader Ayatollah Ali Khamenei is “an enemy of God,” state media has reported.

Grand Ayatollah Naser Makarem Shirazi was responding to a question about any threats made by U.S. President Donald Trump and the leaders of Israel, including prime minister Benjamin Netanyahu.

A fatwa is a ruling on how to interpret Islamic law issued by a clerical authority.
