FBI warns of possible Daesh-inspired attacks in U.S.

U.S. federal authorities cautioned local law enforcement to be aware that supporters of Daesh have been calling for their sympathizers to attack holiday gatherings in the United States, including churches, a law enforcement official said, Reuters reported.

The warning, issued in a bulletin to local law enforcement, said there were no known specific, credible threats. The notice from the Federal Bureau of Investigation and Department of Homeland Security was issued out of an abundance of caution after a publicly available list of U.S. churches was published on pro-Daesh websites.

"The FBI is aware of the recent link published online that urges attacks against U.S. churches. As with similar threats, the FBI is tracking this matter while we investigate its credibility," the FBI said in a statement.

Daesh sympathizers "continue aspirational calls for attacks on holiday gatherings, including targeting churches," CNN quoted the bulletin as saying. The notice describes different signs of suspicious activity for which police should be alert, it said.
