Intelligence Minister Heydar Moslehi said the attack on Iran's nuclear facilities was planned after the talks in Moscow aimed at curtailing Iran's nuclear program broke down.
He didn't say how Iran had detected the attack or where the information came from, but he said the attack was planned by the U.S. and "the Zionist regime" as well as Britain's MI6 intelligence service, .
"They still seek to carry out the plan, but we have taken necessary measures," Moslehi said, according to the report.
The New York Times earlier this month that President Barack Obama had ordered attacks on the computers that run Iran's nuclear facilities, accelerating a plan that began before he came to office. That led to the infamous Stuxnet virus that targeted Iran's Natanz plant, according to the Times.
Press TV also cited a Washington Post that said the U.S. and Israel had cooperated on a new virus, called Flame, to target Iran's nuclear program.
