“Prior to ISIS’s terrorist attack on January 3, 2024, in Kerman, Iran, the U.S. government provided Iran with a private warning that there was a terrorist threat within Iranian borders,” a U.S. official said. “The U.S. government followed a longstanding ‘duty to warn’ policy that has been implemented across administrations to warn governments against potential lethal threats. We provide these warnings in part because we do not want to see innocent lives lost in terror attacks.”
