Alleged Nazi war criminal John Demjanjuk has arrived in Germany after being deported from the US, police say.The frail 89-year-old is due to face charges in the southern city of Munich of being an accessory to the deaths of 29,000 Jews during World War II. He denies accusations that he worked as a guard in the Sobibor Nazi death camp. Mr Demjanjuk, who settled in the US in 1952, says he was captured by the Germans in his native Ukraine during the war and kept as a prisoner of war.
