TEHRAN, Iran (AP) - Iran's president has confirmed for the first time that a computer worm affected centrifuges in the country's uranium enrichment program.

Iran has previously denied the Stuxnet Worm, which experts say is calibrated to destroy centrifuges, had caused any damage, saying they uncovered it before it could have any effect.

But President Mahmoud Ahmadinejad has said it “managed to create problems for a limited number of our centrifuges.'' Speaking to a press conference Monday, he said the problems were resolved.

Earlier in November, U.N. inspectors found Iran's enrichment program temporarily shut down, according to a recent report by the U.N. nuclear watchdog. The extent and cause of the shutdown were not known, but speculation fell on Stuxnet.
