“Mossad chief Meir Dagan promised to block Iran's nuclear program, shortly after taking the job more than six years ago," said a recent article published in the Israeli Ha'aretz daily.
According to the article, Dagan failed to keep his promise despite placing Iran higher on the list of Mossad's 'essential' intelligence-gathering targets.
The paper said that Dagan had allocated a substantial percentage of the Israeli 'intelligence operations' budget to sabotaging the Iranian nuclear program.
To infiltrate Iranian nuclear facilities, Mossad created undercover companies that initially sold Iran bona-fide equipment to establish trust, and then supplied equipment fitted with listening devices.
Ha'aretz said that Israeli spy, Ali Ashtari, was recently executed in Iran after confessing to cooperating with Mossad and selling bugged internet cables and satellite phones to targeted Iranian officials.
News of Mossad's elevated campaign against Iran follows the high profile arrest of a number of Israeli spies in the Islamic Republic.
Two weeks ago, Iran's intelligence forces cracked a spy network that had been gathering information for Israel. During the operation, they arrested three men who had received extensive training near Tel Aviv.
The men were trained by Israel on the use of satellite and computer equipment for intelligence operations and prepared for terror attacks against Iran.
