The Department of Homeland Security (DHS) on Aug. 13 issued a new national terrorism bulletin, warning of a “heightened threat environment” across the United States as the 20th anniversary of the 9/11 terrorist attacks approaches.
The United States continues to face “diverse and challenging” threats, according to the DHS. Those threats include domestic terrorist activities by individuals or groups engaged in “grievance-based violence,” and those motivated by foreign terrorists and other malign foreign influences.
