Warns of a credible terrorism 

threat against the United States. 

Warns of a credible, specific and 

impending terrorism threat 

against the United States.

ADDITIONAL DETAILS 

 Since issuing the first Bulletin in December, our concerns that violent extremists 

could be inspired to conduct attacks inside the U.S. have not diminished. 

 Though we know of no intelligence that is both specific and credible at this time of a 

plot by terrorist organizations to attack the homeland, the reality is terrorist-inspired 

individuals have conducted, or attempted to conduct, attacks in the United States. 

 DHS is especially concerned that terrorist-inspired individuals and homegrown 

violent extremists may be encouraged or inspired to target public events or places. 

 As we saw in the attacks in San Bernardino, Paris, Brussels, and, most recently, 

Orlando, terrorists will consider a diverse and wide selection of targets for attacks. 

 Terrorist use of the Internet to inspire individuals to violence or join their ranks 

remains a major source of concern. 

 In the current environment, DHS is also concerned about threats and violence 

directed at particular communities and individuals across the country, based on 

perceived religion, ethnicity, nationality or sexual orientation. 

U.S. GOVERNMENT COUNTERTERRORISM EFFORTS 

 DHS and the FBI continue to provide guidance to state and local partners on increased 

security measures. The public may observe an increased law enforcement and 

security presence across communities, in public places and at events in the months ahead. This may include additional restrictions 

and searches on bags, more K-9 teams, and the use of screening technologies. 

 The FBI is investigating potential terrorism-related activities associated with this broad threat throughout the United States. 

Federal, state, and local authorities are coordinating numerous law enforcement actions and conducting community outreach to 

address this evolving threat.

SUMMARY

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. 

DURATION

This Bulletin will expire on

November 15, 2016

at 11:59 p.m. 

HOW YOU CAN HELP

 Report suspicious activity to local law 

enforcement or public safety officials who 

are best positioned to respond and offer 

specific details on terroristic indicators. 

 Suspicious activity or information about a 

threat may also be reported to Fusion 

Centers and the FBI’s Field Offices - part of 

the Nationwide Suspicious Activity 

Reporting Initiative.

 Learn how to recognize signs of preoperational planning associated with 

terrorism or other criminal activity.

STAY INFORMED

 The U.S. Government will provide 

additional information about any emerging 

threat as additional information is identified. 

The public is encouraged to listen to local 

law enforcement and public safety officials.

 We urge Americans to continue to travel, 

attend public events, and freely associate 

with others but remain vigilant and aware of 

surroundings.

 The Department of State issues international 

travel alerts and warnings.

BE PREPARED

 Be prepared for increased security and 

plan ahead to anticipate delays and 

restricted/prohibited items. 

 In populated places, be responsible for 

your personal safety. Make a mental 

note of emergency exits and locations of 

the nearest security personnel. Keep cell 

phones in your pockets instead of bags 

or on tables so you don’t lose them 

during an incident. Carry emergency 

contact details and any special needs 

information with you at all times. For
