FBI declines comment on Serbia's 'sound cannon' probe claim

The FBI has refused to comment on Serbian President Aleksandar Vučić's assertion that the agency was asked to investigate the alleged use of a "sound cannon" during a protest on March 15 of the previous year in Belgrade.

According to reports from N1, the FBI responded to inquiries about confirming their involvement and Vučić's statements with a simple "Thank you for reaching out. The FBI declines to comment."

This follows claims in pro-government media that the FBI and Russia's FSB had confirmed that a "sound cannon" was not used during a large student protest on March 15 of the previous year. However, video evidence suggests Vučić stated that the FBI and FSB were invited to "come and determine" the facts.

Serbian Minister of Police Ivica Dačić had reportedly written to the FBI in March of the previous year, but no response was ever made public. The only publicly released report was from Russia's Federal Security Service (FSB) on April 16 of the previous year.

Vučić had previously called on the FBI and other European security services to investigate the alleged use of a "sound cannon." N1 also reported that Vučić had previously dismissed the use of a "sound cannon" at the March 15 protest as a fabrication, claiming that NASA experts had confirmed its non-use. When N1 contacted NASA for confirmation, the agency stated, "NASA does not possess any information."
