him to Singapore where a chemical plant allegedly blew up. After leaving home with his suitcase, he was taken not to the airport but to an apartment in some undisclosed location where he was interrogated harshly and put under psychological pressure to confess. After ten days, Klingberg admitted to being a Soviet mole and signed a confession. He claimed that he had provided information to the Soviet Union only for ideological reasons. Klingberg was tried in secret and sentenced to 20 years in prison. For the first 10 years of his 20-year sentence he was held in solitary confinement, in a high security prison, under a false name and a fabricated profession. After he was removed from solitary confinement, his cellmate was Shimon Levinson, another Israeli who spied for the Soviet Union. In September 1990, Klingberg's wife Wanda died. In accordance with her wishes, she was cremated. Her ashes were buried in the Père Lachaise Cemetery in Paris. Klingberg's motives for spying are not definitively known. Klingberg claimed that he spied out of ideological reasons, and that he was never paid. However, he told his interrogators that he had not completed his medical studies and lacked a diploma, and that the KGB had blackmailed him by threatening to expose this. In an interview after his release, Klingberg maintained that he had spied out of ideological reasons, but had lied to his interrogators and said he had been blackmailed so he would receive a lighter sentence. In an interview in 2014 he said that he also felt he owed the Russians a debt for saving the world from the Nazis. He said he had always been a communist, and had recruited his wife Wanda and two friends. In 1988-89, Israeli attorney Amnon Zichroni, representing the State of Israel, worked out a deal in which Klingberg would be released, and the Soviet Union would release Ron Arad, an Israeli fighter pilot believed to be captured in Lebanon. The deal fell apart. In 1997, Amnesty International appealed to the Israeli government to release Klingberg on medical grounds. Because of his failing health (he had several strokes), he was released to house arrest in October 1998. At his expense, a camera was installed in his apartment, which was hooked up to the offices of MALMAB (Ministry of Defense Security Authority) at the Kirya, Tel Aviv. His telephone was wiretapped, with his knowledge. Special guards
