The FBI and DHS issued a warning to law enforcement nationwide about potential copycat attacks following an ISIS-inspired vehicle ramming attack in New Orleans on New Year’s Day that killed 14 people.

The agencies cautioned about the appeal of vehicle ramming as a tactic for extremists and the possible use of additional weapons like firearms, knives, or IEDs.

The warning urged vigilance and reporting of suspicious activity but noted no specific threats at this time, Fox News has reported.
