Accused Nazi death camp guard John Demjanjuk has been deemed fit enough by medical experts to stand trial for allegedly helping to kill 29,000 Jews in 1943.The 89-year-old was deported to Germany from the US in May, and has been held in a jail near Munich. The medical experts have placed a limit of two 90-minute court sessions per day for Demjanjuk. His family has argued he is too frail to stand trial, saying he has spinal problems, kidney failure and anaemia. Demjanjuk denies any role in the Holocaust. His trial is expected to be Germany’s last major Nazi court case.
