The Department of Homeland Security on Thursday released a new bulletin that said the U.S. is facing a significant, ongoing terror threat.
"We continue to face one of the most challenging threat environments since 9/11, as foreign terrorist organizations exploit the Internet to inspire, enable, or direct individuals already here in the homeland to commit terrorist attacks," the bulletin said.
DHS has issued five iterations of the terror threat bulletin since December 2015.
Acting DHS Secretary Elaine Duke said she directed the organization to make an update to extend this new bulletin for six months.
"Our enemies remain focused on attacking the United States, and they are constantly adapting. DHS and its partners are stepping up efforts to keep terrorists out of America and to prevent terrorist recruitment and radicalization here at home, and we urge the public to remain vigilant and report suspicious activity," Duke said in a statement.
