National Terrorism Advisory Bulletin System Bulletin - August 13, 2021 - Translations
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.
