The trial against a Sobibor Nazi Death camp guard continues. Doctors say John Demjanjuk is fit enough to stand trial in Germany for helping to kill 29.000 Jews during World War Two. His trial is expected to be Germany's final major Nazi war crimes court case. 

The 89-years old was deported from the United States to Germany in May. He is held at Stadelheim jail, where Hitler was held after a failed 1922 coup attempt.

Demjanjuk suffers from spinal problems, kidney failure and anaemia, according to his family. Medical experts limited the court to hold no more than two 90-minute sessions a day.
 
State prosecutors expect charges to be raised against Demjanjuk in July. Both prosecutors in Munich and Demjanjuk's defence attorney, Guenther Maull, says the trial could begin by autumn.

When he arrived in Germany, pictures showed Demjanjuk lying on a stretcher in an ambulance wearing a baseball cap with tubes coming out of his nose.

Born in Ukraine, Demjanjuk tops the list of the International Jewish human rights organisation Simon Wiesenthal Center of its 10 most-wanted suspected war criminals. Munich prosecutors want him tried for assisting in murders at Sobibor extermination camp, in what is now Poland.

He denies any role in the Holocaust.

According to the Wiesenthal Center, Demjanjuk pushed men, women and children into gas chambers.

Demjanjuk has said he was drafted into the Soviet army in 1941, became a German prisoner of war and later became a guard in German prison camps until 1944.

He was stripped of his US citizenship after he was accused in the 1970s of being "Ivan the Terrible", a notoriously sadistic guard at the Treblinka death camp.

He was extradited to Israel in 1986 and sentenced to death in 1988, but Israel's Supreme Court overturned the conviction when new evidence showed another man was probably "Ivan".

He regained his citizenship in 1998, but the US Justice Department refilled its case against him in 1999, arguing he had worked for the Nazis as a guard at three other death camps. His citizenship was stripped from him again in 2002.
