Munich (AP) -- German prosecutors say doctors have determined that John Demjanjuk is fit to stand trial over allegations that he was an accessory to murder at a Nazi death camp.

Munich prosecutors say in a statement Friday that they expect to file formal charges later this month.

They say doctors have determined the 89-year-old is fit to face trial on condition that court sessions do not exceed two 90-minute periods per day.

The retired auto worker is accused of being an accessory to murder in 29,000 cases at the sobibor camp.

The longtime Ohio resident was deported in May after losing a court battle to stay in the United States.
