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.

Additional Details

  • Our concerns that violent extremists could be inspired to conduct attacks inside the U.S. have not diminished.
  • As the U.S. continues to apply pressure against terrorist-affiliated groups overseas, attempts by these groups to inspire or even direct attacks inside the U.S. may increase.
  • 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.
  • The holiday season, in particular, provides additional opportunities for violent extremists to target public events and places where people congregate.
  • 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, local, tribal and territorial partners related to the current threat environment. DHS also partners closely with the private sector to provide risk assessments and coordinate enhanced security measures with business owners and operators. The public may continue to observe increased law enforcement and security presence, particularly around certain holiday celebrations and other large gatherings.
  • 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.
