BELGRADE, March 17. /TASS/. Serbia’s Security Information Agency has denied that the police allegedly used a "sonic weapon" against protesters on March 15.

"Following the false statements about the alleged use of a 'sonic weapon' at a rally on March 15, 2025, the Serbian Security Information Agency stresses that no one used such a weapon and that the agency’s officers on duty on March 15 did not report the deployment of such a device, with no specific sounds being heard and no other effects such a weapon could produce being seen. Our officers did not feel its effects," the agency said, adding that it "has never had such a device."

Serbian Prime Minister Milos Vucevic said earlier on Monday that the government invites Russian and US special services to investigate the alleged use of a "sonic weapon" by the police.

Grass-roots anti-government protests were held in Belgrade on Saturday. According to the Serbian interior ministry, more than 100,000 people took part in them. Anti-government protests have been rocking the country since November 2024 following the November 1, 2024 deadly accident at the Novi Sad railway terminal that killed 15 people. The protesters put the blame for the accident on the country’s government. President Aleksandar Vucic said amid the protests that Serbia would not tolerate any color revolutions like the one in Kiev.

A number of opposition media outlets released videos showing a crowd suddenly scattering to both sides of the street. They claim that such behavior could be explained by the use of some sort of an ultrasound device. Both the country’s police and interior ministry have refuted these reports, denying the use of such devices.
