“The U.S. military has increased security at its bases around the country and at the Pentagon, defense officials said Friday, in part because of potential threats from followers of Islamic State,” The Wall Street Journal reports.  

“Defense officials said the increased security measures weren’t a result of any specific intelligence… The change put security at Force Condition Bravo. The last time the militant went to Bravo level in the U.S. was in 2011 on the 10th anniversary of the Sept. 11 terror attacks. There are four levels, A through D.”  

“Officials said the decision to raise the security level was tied, in part, to the same intelligence that prompted the Federal Bureau of Investigations director to issue a separate warning… FBI Director James Comey said Thursday that his agency has opened investigations into hundreds of potential extremists in the U.S.”
