The Washington Post has revealed the CIA has been operating stealth surveillance drones deep inside Iran for the last three years in an attempt to uncover evidence of an Iranian nuclear weapons program. In addition, the National Security Agency has ramped up eavesdropping on Iran, and the United States has expanded its network of spies inside Iran’s borders. The news comes just days before Turkey hosts talks on Iran’s nuclear program. Last week, investigative journalist Seymour Hersh revealed the U.S. Joint Special Operations Command trained the Iranian opposition group Mujahideen-e-Khalq, or MEK, at a secret site in Nevada even though the group is listed as a foreign terrorist organization by the U.S. State Department. The MEK has been linked to the assassinations of several Iranian nuclear scientists.
