John Demjanjuk, accused of helping to murder more than 27 000 Jews at a Nazi death camp, has gone on trial in the German city of Munich.
Demjanjuk, who is 89 and was deported from the US in May, entered the courtroom in a wheelchair. His eyes were closed but he was conscious.
He denies being a camp guard at Sobibor, in Nazi-occupied Poland, the BBC reported.
The trial is expected to last until May and, if found guilty, Demjanjuk could be sentenced to 15 years in jail.
Witnesses have been arriving for the court session, but organisers were overwhelmed by the crowds of people trying to get in, including journalists and relatives of Holocaust survivors.
