Alleged Nazi war criminal John Demjanjuk has been deported from the US on a plane bound for Germany, BBC reported.
The frail 89-year-old is due to face charges in Germany 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.
The plane carrying him took off from Cleveland airport on Monday evening.
US agents earlier arrived at his family home, removed Mr Demjanjuk in his wheelchair, and drove him to a federal building in Cleveland.
He has been fighting deportation since charges were levelled against him in March, arguing that he is too frail to be moved.
On Thursday, the US Supreme Court rejected a request by Mr Demjanjuk to intervene in the case. One day later he was ordered to surrender to immigration authorities.
US federal agents briefly removed him from his home in April, but a stay of deportation was granted.
A three-judge panel from the 6th US Circuit Court of Appeals in Ohio then ruled that the removal could go ahead, saying it was satisfied that Mr Demjanjuk would be provided with adequate care.
Mr Demjanjuk arrived in the US in 1952 as a refugee, settling in Cleveland, Ohio, where he worked in the car industry.
In 1988 he was sentenced to death in Israel for crimes against humanity after Holocaust survivors identified him as the notorious "Ivan the Terrible", a guard at the Treblinka death camp.
But Israel`s highest court later overturned his sentence, after documents from the former Soviet Union indicated that "Ivan the Terrible" had probably been a different man.
Mr Demjanjuk returned to the US, but in 2002 had his US citizenship stripped because of his failure to disclose his work at Nazi camps when he first arrived as a refugee.
In 2005, a US immigration judge ruled that he could be deported to Germany, Poland or Ukraine.
And in March 2009, German officials issued a warrant for his arrest, accusing him of being an accessory in the deaths of 29,000 Jews.
