Oliver Darcy reports at the Blaze:

The Denver division of the FBI issued an alert to law enforcement in Colorado and Wyoming over suspicious behavior from "Middle-Eastern males" who have approached families members of military personnel in recent weeks.

The bulletin, issued in July but only attracting attention in recent days, cited an incident when the wife of a military member was "approached in front of her home by Middle-Eastern males" who told her that she was "the wife of a US interrogator." The alert said when the woman denied the claim the "men laughed." The individuals eventually left the area, but were seen in the area on other occasions, according to the bulletin.

"The FBI added that similar incidents were reported in Wyoming throughout June," the Blaze reports.

"On numerous occasions family members of military personnel were confronted by Middle Eastern males in front of their homes," the Blaze quotes the alert as saying.

"The males have attempted to obtain personal information about the military men’s family members through intimidation," the FBI alert states, according to the Blaze.

"The FBI said in the bulletin that the men have not been identified and urged individuals to report 'concerning additional incidents," the Blaze reports.

Who might be behind this intimidation? "The Islamic State terror group has on several occasions threatened to strike military members in their homes," the Blaze states.

"In March, a group calling itself the 'Islamic State Hacking Division' posted a list of addresses purportedly belonging to approximately 100 military members. The group called for their beheadings, saying it leaked the information 'so that our bothers residing in America can deal with you'," according to the Blaze.
