Pensacola, Fla. (AP) -- The Saudi gunman who killed three people at the Pensacola naval base had apparently gone on Twitter shortly before the shooting to blast U.S. support of Israel and accuse America of being anti-Muslim, a U.S. official said Sunday as the FBI confirmed it is operating on the assumption the attack was an act of terrorism.

Investigators are also trying to establish whether the killer, 2nd Lt. Mohammed Alshamrani, 21, of the Royal Saudi Air Force, acted alone or was part of a larger plot.
