Iran's enemies used computer code to make "limited" problems for centrifuges involved in uranium enrichment at some of its nuclear sites, President Mahmoud Ahmadinejad said on Monday.

"They succeeded in creating problems for a limited number of our centrifuges with the software they had installed in electronic parts. They did a bad thing. Fortunately our experts discovered that and today they are not able (to do that) anymore," he told a news conference.

Ahmadinejad's comments came less than a week after Iran temporarily ceased uranium production in its nuclear facility in Natanz, apparently due to a series of major technical problems.

Diplomats in Vienna said they had no specifics regarding why Iran had shut down production of thousands of centrifuges enriching uranium.

But suspicions focused on the Stuxnet worm, the computer virus thought to be aimed at Iran's nuclear program, which experts last week identified as being calibrated to destroy centrifuges by sending them spinning out of control.

In Monday's interview with Press TV, the Iranian president also spoke of Sunday's massive leak of U.S. classified cables by whistle-blowing website WikiLeaks, with some of the documents alleging that Arab states had asked Washington to strike Iran's nuclear facilities.

"Regional countries are all friends with each other. Such mischief will have no impact on the relations of countries," the Iranian president said in the interview, alleging that "some part of the American government produced these documents.

"We don't think this information was leaked. We think it was organized to be released on a regular basis and they are pursuing political goals," Ahmadinejad said.

The Iranian president also refereed to upcoming talks over his country's controversial nuclear program, saying Iran's uranium enrichment activities were the country's legal right and will not be negotiated away at talks with world powers that may be held in the coming weeks.
