JERUSALEM (AP) _ The Nazi war crimes trial of retired Ohio autoworker John Demjanjuk will resume Oct. 26, a court spokesman said.

The summer recess was extended when one of the judges on the case, Zvi Tal, suffered a heart attack Sept. 2.

Spokesman Yossi Hassin said Wednesday the judge was in ''satisfactory condition and improving.'' He will remain a member of the three-judge panel that is hearing the case when the trial resumes, Hassin added.

Demjanjuk, who was born in the Ukraine, is charged with being ''Ivan the Terrible,'' a brutal guard who operated the gas chambers at the Treblinka death camp in Nazi-occupied Poland. About 850,000 Jews were killed at the camp in 1942 and 1943.

Demjanjuk, 67, maintains he is a victim of mistaken identity.

The first witness to take the stand next month will be Nikolai Tolstoy, a historian and great grand-nephew of Russian novelist Leo Tolstoy, according to Demjanjuk's Israeli attorney, Yoram Sheftel.

Tolstoy is an expert on a renegade militia called the Vlasov Army, which fought with the Germans against the Soviets at the end of World War II. The defense claims Demjanjuk belonged to that army.

The trial began in February.
