Minority group representatives in Poland have written to the president to express concern about what they see as a rising wave of aggression based on nationality, race and religion.

The leaders of Ukrainian, Tartar, Jewish and other groups said in a letter published by the Polish Press Agency late Saturday they especially oppose recent "numerous and loud manifestations of anti-Semitism."

They attributed the voicing of anti-Semitic remarks to lawmakers' passage of legislation seeking to outlaw statements blaming Poles as a nation for World War II crimes committed by Nazi Germany.

Israel and international Jewish organizations have strongly criticized the proposal.

The opposition sparked anti-Semitic comments on social media in Poland that some members of the ruling Law and Justice party have retweeted.
