Mystery Blasts: Part of Covert Iran War?

Explosions have crippled Iranian gas pipelines and military facilities. Car bombs and gunshots have killed Iranian nuclear physicists. A computer virus stopped centrifuges from enriching uranium. All part of a Western/Israeli shadow war against Iran? Israeli Defense Minister Ehud Barack denies it, but some analysts say the CIA, Mossad, European spies and a dissident Iranian group called MEK have been terrorizing Iran for two years in order to eliminate the need for broader airstrikes, the Los Angeles Times reports.

Some evidence supports the notion. Iran claims to have collared dozens of CIA informants; the CIA admits to a few arrests. And many Western experts say Israel snuck the Stuxnet worm into Iran's nuclear facilities. Former US officials concede that Uncle Sam may be selling Iran bad parts or attacking facilities with malware, but insist a sabotage campaign is outside the CIA's reach. The Mirror, meanwhile, quotes sources who say that the latest Tehran military base explosion may be a prelude to all-out Western airstrikes. (More Iran stories.)
