The FBI and Department of Homeland Security sent out a joint bulletin on Sunday suggesting that "individuals overseas are spotting and assessing like-minded individuals who are willing and capable of conducting attacks against current and former U.S.-based members of the United States military."
U.S. military members are being told to scrub their social media accounts of any material that could make them a target for ISIS, Fox News reports. The warning is the most recent in a series of alerts about potential attacks against service members, and follow from concerns about recent attacks that killed soldiers in Canada, and which appeared to have been planned with online information.
The Army issued a similar warning in October after ISIS militants told supporters to use social media to locate military members and "show up [at their homes] and slaughter them."
The Pentagon also warned employees that they could targeted, and advised them to change travel routes, remove identifiable logos, and not to post anything online that would link them to the Defense Department.
