HONOLULU (AP) Defense Secretary Chuck Hagel is calling the shootings at Fort Hood, Texas, a "terrible tragedy."
In remarks to reporters in Honolulu, Hagel says he is aware of casualties at the Army base in Texas and that the facility remains under lockdown.
U.S. officials tell The Associated Press that one person was killed and 14 were injured in the shooting Wednesday. The officials spoke on condition of anonymity because they were not authorized to discuss the information by name.
Asked about security improvements in the aftermath of other shootings at military bases, Hagel said "something's not working" when such tragedies take place.
