Terrorism advisory bulletin warns of "heightened threat environment" in U.S. [View all]

(CBS News) A bulletin from the National Terrorism Advisory System warns of a "heightened threat environment in the United States" following the U.S. military strikes on Iran's nuclear sites.

The bulletin, first obtained by CBS News on Sunday morning, June 22, does not note any current specific threats, but warns that "low-level cyber attacks against US networks by pro-Iranian hacktivists are likely, and cyber actors affiliated with the Iranian government may conduct attacks against US networks."

While there are no known threats, Secretary of Homeland Security Kristi Noem said, "It is our duty to keep the nation safe and informed, especially during times of conflict."
