The trial of John Demjanjuk, a suspected Nazi concentration camp guard, has been adjourned until 21 December, because the 89-year-old is too ill to attend.

Judge Ralph Alt told Germany's Munich court that the former US car worker, who denies helping kill 27,900 Jews at the Sobibor camp in Nazi-occupied Poland, had shown signs of infection and a slight temperature.

Doctors advised against sending him to court on Thursday.

But Demjanjuk said nothing in the first two days of hearings and appeared in court lying on a hospital bed with his eyes closed or staring blankly. Some victims' families accused him of dramatising his condition.

Demjanjuk was born in Ukraine and fought in the Red Army before being captured by the Nazis and recruited as a camp guard. He emigrated to the United States in 1951.

In May, he was extradited from the US where he had lived in a suburb of Cleveland, Ohio.

Demjanjuk has acknowledged being at other camps but not at Sobibor, which was run by 20 to 30 Nazi SS members and up to 150 former Soviet war prisoners.
