Pensacola, Florida authorities said that on Monday a cyber attack hit the city, just days after a Saudi officer killed three American sailors in the naval base of the city.
The assault targeted accounts, phone lines and online payment systems, the northwest municipality reported on Facebook.
Officials did not say whether the cyber and naval base attacks had a connection.
“We… try to figure out who that is, and… where we go from here to bring our process together,” said Mayor Grover Robinson at the press conference.
City officials also informed the FBI, whose Office in Jacksonville tweeted that it was “providing resources to assist.”
The cyber attack happens as Pensacola is still being shot from the naval base.
A second lieutenant in the Saudi Royal Air Force, Mr Mohammad Alshamrani, opened fire on Friday in a classroom on the naval base at Pensacola killing three sailors and injuring 8 more before being killed by the police.
The 21-year-old was at the center of a Saudi military training programme.
The FBI said on Sunday that it was an act of terrorism that they investigated, but had yet to make a final decision.
