The Department of Homeland Security’s National Terrorism Advisory System today issued an updated bulletin on the global threat environment. While its basic assessment has not changed since the last bulletin in June, the agency said it “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.” The bulletin offers tips for recognizing and reporting suspicious activity, and for staying informed about emerging threats.
