Security conditions at U.S. military bases have been increased over growing concerns about terror threats, officials said Friday.
A U.S. official confirmed to CNN that U.S. military bases are now at "Force Protection Bravo," which is defined by the Pentagon as an "increased and predictable threat of terrorism." It is the third-highest threat level on a five-tier scale used by the Department of Defense.
U.S. military officials added Friday that the announcement, which comes in the aftermath of the shooting at a Texas cartoon contest featuring drawings of the Prophet Mohammed, was not the result of a specific threat but because the military had become concerned about several recent incidents.
The military became alarmed when one of the jihadists linked to the Garland attack tweeted the name and address of a U.S. military officer connected to the military's Syrian rebel training program, a U.S. military official told CNN.
The tweet, first published on an account connected to British-born jihadist Junaid Hussain, was sent out a few days before the attack on the cartoon exhibit and appeared to encourage an attack on the address.
