Iran’s intelligence minister has claimed without offering evidence that Tehran seized an “important treasury” of information regarding Israel’s nuclear program.

The ‘revelation’, if true, could pose serious political and security consequences for Israeli Prime Minister Benjamin Netanyahu’s government, especially at a time when the Middle Eastern region is simmering with tension.

Iran is escalating its fight with the United Nations nuclear watchdog, accusing its inspectors of slander and presenting sloppy evidence, according to a legal brief compiled by the Islamic Republic and circulated among diplomats days before a key meeting in Vienna.
