DHS and FBI Public Service Announcement
Threat Environment
The Department of Homeland Security (DHS) and Federal Bureau of Investigation (FBI) are
issuing this Public Service Announcement to highlight potential threats in the United States from
a variety of actors in response to the HAMAS attacks on Israel on 7 October and subsequent
activities in the region, including additional calls by foreign terrorist organizations to their
supporters seeking to foment violence in the West. This is an update to the 10 October FBI and
DHS Public Service Announcement and the 18 October FBI, National Counterterrorism Center
(NCTC), and DHS Joint Intelligence Bulletin to law enforcement partners.
This announcement
reflects a fluid and evolving situation; the terrorism threat in the Homeland has remained
heightened throughout 2023, but recent events have increased the possibility of potential attacks
against individuals and institutions in response to developments in the Middle East.
Since DHS and FBI issued the 10 October Public Service Announcement, the volume and
frequency of threats to Americans, especially those in the Jewish, Arab American, and Muslim
communities in the United States, have increased, raising our concern that violent extremists and
lone offenders motivated by or reacting to ongoing events could target these communities.
These
threats have included hoax bomb threats targeting houses of worship and violent rhetoric online
encouraging attacks against the Jewish, Arab American, and Muslim communities across the
United States. Of note, on 14 October an individual in Illinois stabbed and killed a six-year-old
Palestinian-American child and severely wounded his mother, an incident that is being
investigated as an anti-Muslim hate crime.
While we have no specific information that foreign adversaries are plotting attacks against the
homeland, some are seeking to take advantage of the conflict, calling for violence in furtherance
of their respective goals. On 13 October, al-Qaida media called for support to HAMAS through
attacks against American bases, airports, battleships, and embassies in predominantly Muslim
countries. On 19 October, an ISIS media posting urged followers to “target the Jewish presence
all over the world…especially Jewish neighborhoods in America and Europe,” and specifically
encouraged attacks on Jewish temples, nightclubs, and economic interests and against “Jewish
and Crusader” embassies. Iranian media outlets have issued and/or amplified various types of
mis- and dis-information online about the conflict in ways that risk deepening resentment and
evoking strong emotional responses among English-speaking audiences. These outlets are
utilizing verifiably doctored or mislabeled images and video footage, inaccurate translations, and
misleading content about the conflict with the apparent intent to stoke passions, accelerate the
process of radicalization, and lead individuals to engage in targeted violence.
Tensions between Israel and the Palestinian territories have long been a source of calls for
violence against Jewish, Arab American, and Muslim communities. This history, coupled with
the current widespread sharing of graphic and disturbing content related to this conflict, increases
the risk of incitement to violence in the United States. We therefore urge everyone to remain
vigilant and to report any threats of violence or suspicious activity to law enforcement.

communities to ensure that available resources are brought to bear.
