Little other information was immediately available about the incident at the military facility in Florida. The sheriff’s office did not say whether there were additional casualties.
The Bureau of Alcohol, Tobacco, Firearms and Explosives said its Pensacola field office was responding to the base. “A search of buildings is being conducted; no word yet on injuries/ victims,” the ATF said on Twitter.
The installation, which hosts 16,000 military personnel and more than 7,000 civilians, is known as the “cradle of Naval aviation.” It’s home to the Navy’s Blue Angels flight demonstration squadron and is the first stop for training to become Naval pilots or flight officers.
The active-shooter reports came just two days after a gunman opened fire at Joint Base Pearl Harbor-Hickam near Honolulu, killing two and injuring a third before shooting and killing himself. The shooter in that incident was identified as an active-duty U.S. Navy sailor and his three victims as civilian Defense Department employees working on the base’s shipyard.
