A fire and an explosion struck a centrifuge production plant above Iran's underground Natanz nuclear enrichment facility early Thursday, analysts said, one of the most-tightly guarded sites in all of the Islamic Republic after earlier acts of sabotage there.

"Theoretically speaking, Israel, the U.S. and others have an interest to stop this Iran nuclear clock or at least show Iran there's a price in going that way," he said. "If Iran won't stop, we might see more accidents in Iran."

Late Thursday, the BBC's Persian service said it received an email prior to the announcement of the Natanz fire from a group identifying itself as the "Cheetahs of the Homeland", claiming responsibility for an attack on the centrifuge production facility at Natanz. This group, which claimed to be dissident members of Iran's security forces, had never been heard of before by Iran experts and the claim could not be immediately authenticated by the AP.
