FBI Bulletin Warns of Islamic State Terrorist Attacks Targeting Homeland Military Community

The FBI issued a strong warning to U.S. military personnel Sunday, urging current and former members of the military to review their social media accounts and exercise "operational security" online to avoid tracking by the Islamic State.

ABC reported that the intelligence bulletin, issued by the FBI and DHS overnight, recommended "current and former members of the military review their online social media accounts for any information that might serve to attract the attention of ISIL and its supporters."

ABC’s Brian Ross said that some members of the U.S. Special Forces "already have deactivated Facebook and other social media accounts" in light of the increased threat.

FBI and DHS officials said they fear "copycat" attacks similar to the terror attack on the Canadian Parliament in October, which was inspired by IS social media propaganda.

Military members are not alone in facing threats from the Islamic State.

On Sunday, an Egyptian IS affiliate claimed responsibility for the death of American petroleum expert William Henderson, 58, who was killed in an alleged carjacking in August.
