Those exposed to the weapon experience sharp ear pain, disorientation and panic, military experts say. Prolonged exposure can cause eardrum ruptures and irreversible hearing damage.
The Belgrade Centre for Security Policy, a non-governmental organization, condemned “the unlawful and inhumane deployment of prohibited weapons, such as acoustic devices, against peaceful protesters.”
“This act represents a blatant display of force and an attempt to incite chaos, aiming to delegitimize protests and criminalize peaceful citizens,” the group said.
Serbian police and the defense ministry denied that the illegal weapon was used.
The Serbian president on Sunday urged judicial authorities to respond to the information “that sonic cannons were used during the protests,” the state RTS broadcaster reported.
“I am asking … the ministry of justice and the prosecutor’s office to react, either to prosecute those who used it, and we know they didn’t but let’s check,” Vucic said. “Let there be a proceeding but then they should also prosecute those who went public with such a notorious lie.”
Belgrade’s emergency hospital has denied reports that many people sought help after the incident and urged legal action against those who “spread untrue information.”
