US and Israel 'used cyberattacks' on Iran

United States media are reporting that Washington has been collaborating with Israel to launch cyberattacks that targeted Iran's nuclear programme. In a report by the New York Times, anonymous US officials confirmed that the National Security Agency, with the help of Israeli experts, may have taken out nearly 1,000 of Iran's 5,000 centrifuges with a sophisticated cyber programme.
