In his first interview on Israeli television, convicted nuclear spy Mordechai Vanunu has revealed how he was caught in a Mossad honeytrap.

Mr Vanunu, who was released in 2004 but still lives under severe security restrictions, told Channel 2 that he met Mossad operative "Cindy" on a street in London.

He said: "I was crossing the road and this woman was crossing the road and we began to talk… I didn't fall in love with her, but I thought things could continue. Initially, I told her she was a Mossad agent, but afterwards I forgot about it."

The pair flew to Rome together. Mr Vanunu said: "It was only when the Mossad people pounced on me in the apartment in Rome that I understood, though for a moment I still thought that she was also a victim. After three days on the ship that brought me to Israel, I came to the conclusion that she was part of the plan."

Mr Vanunu spent 18 years in prison for revealing Israel's nuclear secrets to the Sunday Times.
