“The man accused of plotting with the Iranian military to assassinate the Saudi ambassador in Washington, D.C. pleaded guilty today,” reports ABC News. “Iranian-American Manssor Arbabsiar was arrested in late September 2011 for his alleged role in what U.S. officials said at the time was a plot to commit a ‘significant terrorist attack in the United States.’ The U.S. said Arbabsiar, a 58-year-old from Corpus Christi, Texas, was working for elements of the Iranian government — specifically Iran’s elite military unit the Quds force — when he attempted to hire hitmen from the feared Zetas Mexican drug cartel to carry out the hit on the Saudi ambassador. Arbabsiar allegedly plotted to bomb a popular D.C. restaurant frequented by the ambassador. He didn’t know he’d been speaking to a DEA informant from the start. Arbabsiar originally pleaded not guilty to five counts, including conspiracy to use a weapon of mass destruction and conspiracy to murder a foreign official.”
