After years of legal battles a US federal court has ordered the deportation ofJohn Demjanjuk who is accused of having been a guard at Nazi camps during World War II.The 85-year-old can now be sent back to his native Ukraine. The court ruled that he had failed to prove his claim that he would face prosecution or even torture if deported to his homeland. Demjanjuk was found guilty of lying to gain entry to the US. In an earlier ruling he was stripped of his American citizenship on several grounds including his participation in a Nazi unit in occupied Poland. It was said to be dedicated to exterminating Jews. Demjanjuk has always denied being a Nazi camp guard. He says he was in the Soviet army but spent much of the war as a prisoner of the Germans.
