German prosecutors have formally charged John Demjanjuk with 27,900 counts of being an accessory to murder.

The date of the trial of the Ukrainian-born Demjanjuk, 89, has not yet been confirmed.

Prosecutors accuse Demjanjuk of serving as a guard at the Sobibor camp in Nazi-occupied Poland during World War II, but he has consistently maintained that he was a Red Army soldier who spent World War II as a German prisoner-of-war.
