Israel's Mossad missed at least two chances to capture Nazi fugitive Dr Josef Mengele, who sent hundreds of thousands of Jews, and possibly over a million, to their deaths at Auschwitz, a former agent said Tuesday.

Rafi Eitan, who commanded the audacious capture in 1960 of top Nazi Adolf Eichmann in Argentina, said that during the hunt he and his team discovered Mengele's hideout.

"At the same time as we caught Eichmann, Mengele was living in Buenos Aires. We found his apartment and kept it under observation," he told Israeli public radio as the spy agency declassified its file on operations against the man known to prisoners as the "Angel of Death".

Eitan, 90, said that while the Mossad had Eichmann in a safe house ahead of smuggling him out of Buenos Aires in an El Al plane, the agency's chief, Isser Harel, wanted them to move against Mengele as well, but he argued against the plan.

"I didn't want to carry out two operations at the same time because we had one successful operation in the bag, and in my experience if you try to carry out another one you put them both at risk," Eitan said.

As a compromise he stayed on in Argentina to keep tabs on Mengele, while his teammates took Eichmann, the main architect of the Nazi Holocaust, back to Israel, where he was later tried and hanged.

"Mengele wasn't at home and the neighbors said he would be back in a week," Eitan continued.

"We waited a week but in the meantime his (Eichmann's) capture was announced to the world and Mengele never returned to his apartment in Buenos Aires."

The Mossad team missed him again when he was spotted in Brazil, Eitan added.

"At the end of 1962 Mengele was positively identified at a farm near Sao Paulo."

But Mossad chief Isser Harel resigned early the next year and his successors did not approve an operation against Mengele as they had other priorities around the world, he said.

Yediot Ahronot's Ronen Bergman told Israeli army radio in an interview that the Mossad files revealed some embarrassing slips, such operatives looking for Mengele "for a large part of the time in Paraguay when in fact he wasn't there," but actually in Brazil.

He wrote in the paper that there was also a costly 1983 operation in West Berlin to bug and follow Mendel's son Rolf in the hope that he would lead agents to his father.

The Mossad also deployed an "intelligent and attractive" female agent posing as a private secretary to try and get close to Rolf and pry information from him, he wrote, but without success.

He quoted the Mossad archive as listing another plan, not implemented, where a caller claiming to be a close friend of Mengele would call Rolf and tell him that his father was gravely ill and he should go to him at once.

Unknown to the Mossad, Josef Mengele had died in a drowning accident in Brazil in 1979. His death was only confirmed in 1985, after his body was exhumed.
