Hungarian prosecutors say they have indicted a 98-year-old man on charges that he abused Jews and assisted in their deportation to Nazi death camps during World War Two.
Lazslo Csatary, who was detained by Hungarian authorities last year, has denied the charges.
He was arrested on information provided by the Simon Wiesenthal Center, a Jewish organization active in hunting down Nazis who have yet to be brought to justice.
The Hungarian prosecution office said Csatary's trial is expected to start within three months.
Last year, the Wiesenthal Center named Csatary as its most wanted war crimes suspect.
The Nazi-hunting organization says the former senior Hungarian police officer helped organize the deportation of thousands of Jews to the Auschwitz death camp in 1944.
The Simon Wiesenthal Center said of Csatary that "the passage of time in no way diminishes his guilt and old age should not afford protection for Holocaust perpetrators."
