Mossad-KGB double agent Zeev Avni dies at 86 by Yossi Melman for Haaretz

Zeev Avni, who was involved in one of Israel's most secret espionage affairs, died last week at age 86.

Avni, a Mossad agent, was arrested in April 1956 on suspicion of being a KGB agent. It emerged that while he was cultivating former Nazis employed as military advisers by Egypt's army for the Mossad, he was also serving as a long-term Soviet mole.

When Avni's double life was eventually exposed, he was tried in secret and sentenced to 14 years' imprisonment.
