Additional Details

• We face one of the most serious terror threat environments since the 9/11 attacks as foreign terrorist organizations continue to exploit the Internet to inspire, enable, or direct individuals already here in the homeland to commit terrorist acts.
• Homegrown terror suspects are increasingly relying on technology, such as end-to-end encrypted social media applications, to avoid detection.  Moreover, terrorist groups are urging recruits to adopt easy-to-use tools to target public places and events. Specific attack tactics have included the use of vehicle ramming, small arms, straight-edged blades or knives, and homemade explosives, as well as other acts such as taking hostages.
• As the United States steps up efforts to disrupt and defeat terrorist groups overseas, we will continue to face a multi-faceted threat environment.
• Specifically, continued successes aimed at disrupting and defeating terrorist groups overseas may encourage homegrown terrorists inside the United States to carry out acts of violence.
• Additionally, foreign terrorist fighters, who have acquired training and battle-tested terrorism experience, are likely to flee from terrorist-controlled territories with a desire to conduct attacks elsewhere, including the United States. Some of these individuals may be U.S. citizens or citizens of other nations attempting to travel to the United States on visas, from visa-waiver countries, with the aim of attacking the homeland or inciting others within our borders to conduct attacks.

U.S. Domestic 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 security measures with business owners and operators. The public may continue to observe law enforcement and security activity in and around public places and events.
• DHS is taking steps to address the threat from foreign terrorist fighters who have traveled or attempt to travel to the United States, including working closely with the FBI and Intelligence partners to identify U.S. persons who left the country to join terrorist groups, as well as putting in place enhanced screening and vetting measures to detect travelers with potential terrorist connections.
• More broadly, we remain committed to preventing violence and threats meant to intimidate or coerce specific populations on the basis of their religion, ethnicity, or identity, and we will seek justice against the perpetrators of such acts.
