Australia’s ABC News reports: Suspected Mossad agent Ben Zygier was arrested by his own spymasters after they believed he told Australia’s domestic intelligence agency about every aspect of his work with the Israelis, sources say.

The ABC’s Foreign Correspondent program understands that Zygier met with ASIO officers in Australia and gave comprehensive detail about a number of Mossad operations, including plans for a top-secret mission in Italy that had been years in the making.

It is unknown who initiated the contact.

Sources have told the ABC that on one of four trips back to Australia in the years before his death in 2010, Mr Zygier – who also used the surnames Alon, Allen and Burrowes – applied for a work visa to Italy.

Last week, Foreign Correspondent revealed Mr Zygier was secretly jailed in Israel’s Ayalon prison, where it is claimed he committed suicide after 10 months in prison.

His incarceration was a state secret in Israel; the security services going to extraordinary lengths to conceal his plight.

The ABC now understands Mr Zygier was one of three Australian Jews who changed their names several times, taking out new passports for travel in the Middle East and Europe in their work for Mossad.

Foreign Correspondent has been told Mr Zygier set up a communications company in Europe for Mossad, a venture that employed the two other Australian dual citizens.

The company exported electronic components to Arab countries as well as Iran.
