Israel announced Friday it was using every available plane and even allowing flights on the Sabbath to bring in a new wave of Soviet Jews fearing political turmoil in their homeland.

The number of Soviet Jews immigrating to Israel - already at its highest level in decades - has nearly doubled in the past three days, officials said. They expect as many as 6,000 to arrive between Thursday and Sunday."No doubt the growing wave is in part a response to the worsening situation in the Soviet Union and the debilitation of the government," said Jewish Agency Chairman Simcha Dinitz. The Jewish Agency oversees immigration.

Dinitz also cited improved transportation arrangements as reasons behind the latest rush of immigrants.
