The Harrisburg International Airport's public address system was hacked on Oct. 14, with a "political statement" aired over the loudspeaker to travelers, according to airport officials.

"An unauthorized user gained access to our PA system and they played an unauthorized recorded message," Scott Miller, a spokesperson for the airport told USA TODAY. He added that the message "was not a threat to the airport."

Airport operations remained normal, although a Delta Air Lines flight – which was boarding at the time of the message's airing – was delayed out of caution. The aircraft was searched and was able to depart.

"Turkish hacker Cyber Islam was here," said the message over the PA system, according to a post on X. It also can be heard saying, "Free Palestine" and profanities relating to President Donald Trump and Israeli Prime Minister Benjamin Netanyahu.

The message played on a loop for about 10 minutes, starting at around 5:42 p.m., according to Miller. The airport's IT department unplugged the PA system, found the message and turned it over to law enforcement.

As of Oct. 16, it's unknown who hacked the airport or their motive. State and federal authorities are currently investigating the incident.

There are also reports of the recording being played in several other Canadian airports, including Kelowna International Airport and Victoria International Airport in British Columbia, as well as Windsor International Airport in Ontario.

On Oct. 15, U.S. Transportation Secretary Sean Duffy posted about the incident on X: "This is absolutely unacceptable and understandably scared travelers." He added that he's coordinating with HIA and the Federal Aviation Administration to "get to the bottom of this hack."
