Mossad, British secret services and the CIA extracted an Iranian nuclear scientist out of Tehran and provided him with a safe haven in the US, the Daily Mail reported on Sunday.
"It was determined infiltrating him into a group of fellow migrants preparing to cross the Channel by boat offered one solution," a British secret service official told the Daily Mail.
Once in the UK, the man was questioned about the current status of the Iranian nuclear program and flown to the US.
The scientist reportedly also helped with the 2012 assassination of another Iranian nuclear scientist, Mostafa Ahmadi Roshan.
Israel is said to have launched a secret operation to dissuade scientists from taking part in the Iranian nuclear program by eliminating those it deemed valuable.
