The Soviet press is striking back at Western reports of Soviet repression by publishing its own dispatches about "dissidents" in America.

The Soviet accounts focus on American Indians, blacks, Communists, antiwar activists and the "tens of thousands" of Americans who are alleged victims of "the witch-hunters of the CIA and FBI."

This kind of coverage is not new to the Soviet press but the suddenly increased volume -- two or three stories a day -- is a marked departure from past practice.

In Soviet eyes, Britain has also recently become another of the archvillains of the capitalist world, trampling on human rights at home while proclaiming concern for civil liberties abroad. These charges have been a theme in dozens of articles in the daily Soviet press and in television news reports discussing the situation in Northern Ireland.

News agencies reported these other developments.

In Frankfurt, West Germany, Heinrich Boell, Guenther Grass and other West German writers appealed to the Czechoslovak general prosecutor to release four dissidents arrested last month.

In Milan, expatriate Soviet chess grandmaster Victor Korchnoi expressed fears over unspecified "dangers" in Italy where he is to compete in a world tournament.

Nearly 150 Jews in 12 Soviet cities staged sit-in demonstrations at their local parliaments demanding written explanations for the government's refusal to permit them to emigrate, Jewish sources said.
