“The FBI issued a warning Sunday to members of the U.S. military that ISIS is calling for attacks against them, according to a law enforcement source, saying that ‘overseas based individuals are looking for like-minded individuals in the US to carry out these attacks.’
‘We also request members of the military review their online social media presence for any information that might attract the attention of violent extremists,’ the bulletin said, advising that members of the military ‘use caution and practice operational security when posting.'”
