The US military bolstered security at bases across the country Friday after the FBI voiced concern that extremists could target troops or police officers.
The head of US Northern Command, Admiral William Gortney, ordered the heightened alert “as a prudent measure,” Pentagon spokesperson Colonel Steven Warren said.
The move, he said, was designed “to remind installation commanders at all levels within the NORTHCOM area of responsibility to ensure increased vigilance in safeguarding of all Defense Department (DoD) personnel and facilities.”
This raised the official alert status one notch higher on a five-point scale, from the fourth level “Alpha” to the third level “Bravo,” which the military describes as an “increased and predictable threat of terrorism.”
Officials said most of the additional security measures would likely not be readily apparent to the public, apart from perhaps more bags being searched or ID cards being checked at base entrances.
The move came after two men attempted to storm an exhibition on Sunday showing caricatures of the Prophet Muhammad (PBUH) in a Dallas suburb.
The two heavily-armed gunmen were shot dead by a local police officer before they could approach the building where the event was being held.
Pentagon chief Ashton Carter said on Thursday that the two assailants had been “inspired” — but not directed — by the Islamic State (IS) group to stage the failed attack.
“The decision to do this now is informed by a generally heightened threat level,” Warren told reporters.
“We’ve seen what happened in Texas. We’ve seen other social media and Internet-based discussions and threats. We have detected a general increase in the overall (threat) environment.”
FBI Director James Comey reportedly said on Thursday that authorities were concerned about the IS group encouraging attacks on “the uniformed military and law enforcement” via online propaganda.
There are “hundreds, maybe thousands” of people in the United States who had received recruitment messages from the militants, Comey said.
