Robert Singer, CEO of the New York-based group, said in a statement that "Jews are deeply disturbed by this ghastly revival of medieval anti-Semitism that led to unimaginable violence and suffering."
Residents, among them children, beat and burned the effigy in the southeastern town of Pruchnik on Good Friday. The figure represented Judas, the discipline of Christ who betrayed him according to the New Testament.
Poles also expressed their disgust at the revival of the anti-Semitic ritual. Some posted photos online of the same ritual being carried out before World War II.
