Calls were mounting in Serbia on Monday for an independent investigation into reports that security forces used a prohibited sonic weapon on crowds at a huge peaceful anti-corruption rally last weekend, even though authorities vehemently denied it.
Serbian rights groups and opposition officials allege that such a weapon that emits a targeted beam to temporarily incapacitate people was used at the protest Saturday, even though it is banned in Serbia. They said they will file charges with international and domestic courts against those who ordered the attack.
