NATIONAL TERRORISM ADVISORY SYSTEM
The National Terrorism Advisory System (NTAS) is designed to communicate
information about terrorist threats by providing timely, detailed information to
the American public. All Americans share responsibility for the nation's
security, and should always be aware of the heightened risk of terrorist attack
in the United States and what they should do.
This page contains current NTAS advisories (both Alerts and Bulletins), archived
copies of expired advisories, and additional information on the NTAS system.
DHS replaced the color-coded alerts of the Homeland Security Advisory System
(HSAS) with the National Terrorism Advisory System (NTAS) in 2011.

The United States remains in a heightened threat environment. Lone offenders and
small groups motivated by a range of ideological beliefs and personal grievances
continue to pose a persistent and lethal threat to the Homeland. Both domestic
violent extremists (DVEs) and those associated with foreign terrorist
organizations continue to attempt to motivate supporters to conduct attacks in
the Homeland, including through violent extremist messaging and online calls for
violence. In the coming months, factors that could mobilize individuals to
commit violence include their perceptions of the 2024 general election cycle and
legislative or judicial decisions pertaining to sociopolitical issues. Likely
targets of potential violence include US critical infrastructure, faith-based
institutions, individuals or events associated with the LGBTQIA+ community,
schools, racial and ethnic minorities, and government facilities and personnel,
including law enforcement.

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.

National Terrorism Advisory System Bulletin - June 7, 2022 | View PDF Version
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 07, 2022 | View PDF

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. While the conditions underlying the heightened threat
landscape have not significantly changed over the last year, the convergence of
the following factors has increased the volatility, unpredictability, and
complexity of the threat environment: (1) the proliferation of false or
misleading narratives, which sow discord or undermine public trust in U.S.
government institutions; (2) continued calls for violence directed at U.S.
critical infrastructure; soft targets and mass gatherings; faith-based
institutions, such as churches, synagogues, and mosques; institutions of higher
education; racial and religious minorities; government facilities and personnel,
including law enforcement and the military; the media; and perceived ideological
opponents; and (3) calls by foreign terrorist organizations for attacks on the
United States based on recent events.

National Terrorism Advisory System Bulletin - November 10, 2021 | View PDF

The Secretary of Homeland Security has issued an updated National Terrorism
Advisory System (NTAS) Bulletin regarding the current heightened threat
environment across the United States. The Homeland continues to face a diverse
and challenging threat environment as it approaches several religious holidays
and associated mass gatherings that in the past have served as potential targets
for acts of violence. These threats include those posed by individuals and small
groups engaged in violence, including domestic violent extremists (DVEs) and
those inspired or motivated by foreign terrorists and other malign foreign
influences. These actors continue to exploit online forums to influence and
spread violent extremist narratives and promote violent activity. The ongoing
global pandemic continues to exacerbate these threats, in part due to perceived
government overreach in implementation of public health safety measures.
Further, foreign terrorist organizations and DVEs continue to attempt to inspire
potential followers to conduct attacks in the United States, including by
exploiting recent events in Afghanistan. As of November 10, 2021, DHS is not
aware of an imminent and credible threat to a specific location in the United
States.

National Terrorism Advisory System Bulletin - August 13, 2021 | View PDF Version
The Secretary of Homeland Security has issued a new National Terrorism Advisory
System (NTAS) Bulletin regarding the current heightened threat environment
across the United States. The Homeland continues to face a diverse and
challenging threat environment leading up to and following the 20th Anniversary
of the September 11, 2001 attacks as well religious holidays we assess could
serve as a catalyst for acts of targeted violence. These threats include those
posed by domestic terrorists, individuals and groups engaged in grievance-based
violence, and those inspired or motivated by foreign terrorists and other malign
foreign influences. These actors are increasingly exploiting online forums to
influence and spread violent extremist narratives and promote violent activity.
Such threats are also exacerbated by impacts of the ongoing global pandemic,
including grievances over public health safety measures and perceived government
restrictions.

The Secretary of Homeland Security has issued a new National Terrorism Advisory
System (NTAS) Bulletin regarding the current heightened threat environment
across the United States. The Homeland is facing threats that have evolved
significantly and become increasingly complex and volatile in 2021. These
threats include those posed by domestic terrorists, individuals and groups
engaged in grievance-based violence, and those inspired or influenced by foreign
terrorists and other malign foreign influences. Social media and online forums
are increasingly exploited by these actors to influence and spread violent
extremist narratives and activity. Such threats also are exacerbated by the
impacts from the ongoing global pandemic.

National Terrorism Advisory System Bulletin - January 27, 2021; Updated April
26, 2021 | View PDF Version
The Acting Secretary of Homeland Security issued a National Terrorism Advisory
System (NTAS) Bulletin, subsequently extended by the Secretary of Homeland
Security, due to a heightened threat environment across the United States, which
DHS believes will persist in the weeks following the successful Presidential
Inauguration. Information suggests that some ideologically-motivated violent
extremists with objections to the exercise of governmental authority and the
presidential transition, as well as other perceived grievances fueled by false
narratives, could continue to mobilize to incite or commit violence.
The expiration date for this Bulletin is extended from April 30, 2021 to May 15,
2021.

Iran likely views terrorism as an option to deter or retaliate against its
perceived adversaries. At this time, we have no information indicating a
specific, credible threat to the Homeland; however, we remain concerned about
Iran’s potential to carry out cyber attacks. Additionally, Iran and its
partners, such as Hizballah, have demonstrated their capability to conduct
various operations in the U.S.

The United States designated Iran a “State Sponsor of Terrorism” in 1984 and
since then, Iran has actively engaged in or directed an array of violent and
deadly acts against the United States and its citizens globally. The United
States designated Iran’s Islamic Revolutionary Guard Corps (IRGC) a Foreign
Terrorist Organization on April 15, 2019 for its direct involvement in terrorist
plotting.

Since the last NTAS Bulletin issued in June 2016, our basic assessment of the
global threat environment has not changed. We remain concerned about homegrown
violent extremists who could strike the homeland with little or no notice.
Events since the last NTAS Bulletin reinforce this. Accordingly, increased
public vigilance and awareness continue to be of utmost importance. This was,
for example, a crucial component of the swift response to the September
terrorist acts in New York City and New Jersey.

In December, we described a new phase in the global threat environment, which
has implications on the homeland. This basic assessment has not changed. In this
environment, we are particularly concerned about homegrown violent extremists
who could strike with little or no notice. The tragic events of Orlando several
days ago reinforce this. Accordingly, increased public vigilance and awareness
continue to be of utmost importance. This bulletin has a five-month duration and
will expire just before the holiday season. We will reassess the threats of
terrorism at that time.

We are in a new phase in the global threat environment, which has implications
on the homeland. Particularly with the rise in use by terrorist groups of the
Internet to inspire and recruit, we are concerned about the “self-radicalized”
actor(s) who could strike with little or no notice. Recent attacks and attempted
attacks internationally and in the homeland warrant increased security, as well
as increased public vigilance and awareness.

HOW CAN YOU HELP?
NTAS advisories – whether they be Alerts or Bulletins – encourage individuals to
follow the guidance provided by state and local officials and to report
suspicious activity. Where possible and applicable, NTAS advisories will include
steps that individuals and communities can take to protect themselves from the
threat as well as help detect or prevent an attack before it happens.
Individuals should review the information contained in the Alert or Bulletin,
and based upon the circumstances, take the recommended precautionary or
preparedness measures for themselves and their families.
Individuals should report suspicious activity to local law enforcement
authorities. Often, local law enforcement and public safety officials will be
best positioned to provide specific details on what indicators to look for and
how to report suspicious activity. The “If You See Something, Say Something®”
campaign across the United States encourages the public and leaders of
communities to be vigilant for indicators of potential terroristic activity, and
to follow the guidance provided by the advisory and/or state and local officials
for information about threats in specific places or for identifying specific
types of suspicious activity.
