Poland's military authorities reimposed security restrictions on the country following Monday's nationwide street clashes.
The overnight curfew, lifted on Sunday after five months, was reinstated in Warsaw and other cities. Telephone connections in the capital and other centers were suspended. In some places use of personal cars was forbidden. All student clubs, discos, and public places of entertainment were ordered shut.
The action came after the Polish leader, Gen. Wojciech Jaruzelski, summoned an emergency meeting of top advisers to discuss street disturbances in Warsaw, Gdansk, Szczecin, Elblag, Torun, Lublin, Krakow, Gliwice, and elsewhere.
Interior Minister Czeslaw Kiszczak told Parliament that 51 riot police were injured in Warsaw and 1,372 people detained. All will be tried according to martial law provisions, he added.
At Gdansk, where Solidarity was born in the summer of 1980, several thousand people tried to take over the city center and attacked the main police headquarters. Authorities blamed antisocialist elements, backed by Western radio stations heard in Poland, for the clashes.
