In a sign of alarm over developments in Poland, the main Soviet newspapers today resumed stinging attacks on the independent trade union Solidarity, accusing it of creating "a sharply worsening situation in a majority of regions of the country."

The armed forces daily Krasnaya Zvezda compared the Polish situation to that existing in Chile before the military coup that overthrew the leftist government of president Salvador Allende in 1973.

The commentaries suggest that Moscow is apprehensive about an apparent impasse in Poland between the Communist government and the independent union.

For several weeks the Soviets have not published any attacks on Solidarity. There was an impression in diplomatic circles here that Moscow had expected that industrial unrest in Poland would subside during the winter months. Privately Soviet officials have made it clear that they were dissatisfied with party leader Wojciech Jaruzelski because of his refusal to pursue a more assertive policy toward the union.

The prospect of a new round of industrial turmoil, however, has generated a spate of sharply critical comments.

The government newspaper Izvestia asserted tonight that Solidarity's leadership has advanced "unacceptable solutions" that would "practically bring under its control the key positions in the country."

Izvestia said Solidarity's recent meeting in Radom, which threatened a general strike if the government took harsh measures against the union, sets Solidarity "on an open struggle for power and the destruction of Poland's state and socialist order."

The armed forces daily said that the union's goal was gradually to weaken and destroy Poland's communist system.

Calling Solidarity a haven for counterrevolutionary forces, Krasnaya Zvezda said, "They are obviously drawing on the experiences of the Chilean counterrevolutionaries who placed their hopes on the fact that the more discontent there is, the easier it becomes to utilize it in the battle against people's power."

The commentaries said that Solidarity had already managed to cripple industries and agriculture and was now trying to seize control of the mass media.

The government news agency Tass said tonight that the union has called for an open challenge to "the legitimate bodies of authority and the party."
