The FBI said Monday it has found no signs of any link between a cyberattack on computer systems of a Florida Panhandle city and last week's attack at the naval air station there in which a Saudi flight student killed three sailors and wounded eight others.

Officials in the city of Pensacola became aware of the cyberattack early Saturday, hours after Friday's shooting at the Pensacola Naval Air Station. Much of the city's computer system remained offline Monday morning, and federal authorities were alerted to the cyberattack as a precaution.
