DHS Issues National Terrorism Advisory System (NTAS) Bulletin

Secretary of Homeland Security Alejandro N. Mayorkas issued a National Terrorism Advisory System (NTAS) Bulletin regarding the continued heightened threat environment across the United States.

Last Updated: | Publication

National Terrorism Advisory System Bulletin - November 30, 2022 - Translations

The United States remains in a heightened threat environment. Lone offenders and small groups motivated by a range of ideological beliefs and/or personal grievances continue to pose a persistent and lethal threat to the Homeland.  Domestic actors and foreign terrorist organizations continue to maintain a visible presence online in attempts to motivate supporters to conduct attacks in the Homeland.  Threat actors have recently mobilized to violence, citing factors such as reactions to current events and adherence to violent extremist ideologies. In the coming months, threat actors could exploit several upcoming events to justify or commit acts of violence, including certifications related to the midterm elections, the holiday season and associated large gatherings, the marking of two years since the breach of the U.S. Capitol on January 6, 2021, and potential sociopolitical developments connected to ideological beliefs or personal hostility. Targets of potential violence include public gatherings, faith-based institutions, the LGBTQI+ community, schools, racial and religious minorities, government facilities and personnel, U.S. critical infrastructure, the media, and perceived ideological opponents.

DHS Issues National Terrorism Advisory System (NTAS) Bulletin, November 30, 2022

On November 30, 2022, Secretary of Homeland Security Alejandro N. Mayorkas issued a National Terrorism Advisory System (NTAS) Bulletin regarding the continued heightened threat environment across the United States.

National Terrorism Advisory System Bulletin - June 7, 2022 - Translations

The United States remains in a heightened threat environment, as noted in the previous Bulletin, and several recent attacks have highlighted the dynamic and complex nature of the threat environment.  In the coming months, we expect the threat environment to become more dynamic as several high-profile events could be exploited to justify acts of violence against a range of possible targets. These targets could include public gatherings, faith-based institutions, schools, racial and religious minorities, government facilities and personnel, U.S. critical infrastructure, the media, and perceived ideological opponents.  Threat actors have recently mobilized to violence due to factors such as personal grievances, reactions to current events, and adherence to violent extremist ideologies, including racially or ethnically motivated or anti-government/anti-authority violent extremism.  Foreign adversaries—including terrorist organizations and nation state adversaries—also remain intent on exploiting the threat environment to promote or inspire violence, sow discord, or undermine U.S. democratic institutions.  We continue to assess that the primary threat of mass casualty violence in the United States stems from lone offenders and small groups motivated by a range of ideological beliefs and/or personal grievances.

National Terrorism Advisory System Bulletin - February 7, 2022 - Translations

The Secretary of Homeland Security has issued an updated National Terrorism Advisory System (NTAS) Bulletin regarding the continued heightened threat environment across the United States. The United States remains in a heightened threat environment fueled by several factors, including an online environment filled with false or misleading narratives and conspiracy theories, and other forms of mis- dis- and mal-information (MDM) introduced and/or amplified by foreign and domestic threat actors. These threat actors seek to exacerbate societal friction to sow discord and undermine public trust in government institutions to encourage unrest, which could potentially inspire acts of violence. Mass casualty attacks and other acts of targeted violence conducted by lone offenders and small groups acting in furtherance of ideological beliefs and/or personal grievances pose an ongoing threat to the nation.
