John Demjanjuk is back in court after two trial sessions were canceled for health reasons.
The court doctor says Demjanjuk received a blood transfusion because of low hemoglobin levels but is again fit for trial.
Ukrainian-born Demjanjuk, 90, is accused of 28,060 counts of accessory to murder for allegedly serving as a guard in the Nazis' Sobibor death camp. He rejects the charges, saying he never served as a guard in any Nazi camp.
The court on Thursday read aloud a statement from former Sobibor prisoner Dov Freiberg _ who is now dead _ from 1976.
Freiberg told authorities he was assigned to clean the Sobibor barracks where the Ukrainian guards were housed, and that he does not remember any Demjanjuk.
