Georgian media report the three were detained on March 20 at the rally to protest official election results giving President Alyaksandr Lukashenka a third term in office. They were reportedly waving Georgian and Belarusian flags.
Givi Targamadze, chairman of Georgia's parliamentary Defense and Security Committee, accused Belarusian authorities of stirring up "anti-Georgian hysteria."
Georgian officials have called on Belarus to release the three.
