Iran’s early Monday missile attack on Islamic State positions in Syria was actually a threat to the U.S., Israel, and Saudi Arabia.

Iran says it carried out the attack in response to a 2017 ISIS attack in Tehran. But according to the Iranian government news site Fars, the missiles employed were short-range ballistic missiles of the Qiam and Zolfaqar variants. Launched by the revolutionary guards, or IRGC, from western Iran, the missiles are assessed to have a range of up to 750 kilometers.
