In an unprecedented joint intelligence bulletin, the FBI and Department of Homeland Security say they have intelligence that IS is trying to recruit people in the United States to target members of the military. They are using social media to track military personnel down. The FBI warned members of the US military to protect themselves by erasing all information on social media accounts that could help ‘violent extremists’ learn their identities. It's the strongest warning to date about possible attacks by IS. Brad Garrett, a former FBI agent, said, ‘We understand that you are young, you communicate through social media, but we are telling you that's how IS finds people they potentially target.’
