Terrorism advisory bulletin warns of “heightened threat environment” in U.S. after strikes on Iran

The U.S. Department of Homeland Security has issued a public warning of a “heightened threat environment” following recent U.S. military strikes on Iran’s nuclear sites. While no specific threats have been identified, officials caution that pro‑Iranian hackers may launch cyberattacks, and there is an increased risk of violence, hate crimes, and extremist activity in the U.S. The bulletin also warns of possible retaliation if Iranian leadership calls for violence, CBS News has reported. Security has been tightened in major cities like New York, and the State Department has issued a global travel alert for Americans abroad.
