Iranian-American pleads guilty to plot to kill Saudi envoy

AFP- Judge John Keenan asked Arbabsiar: "Is it true that about the spring of 2011 up until the fall of 2011 that you and your co-conspirators... who were officials in the Iranian military, that you agreed to cause the assassination of the Saudi Arabian ambassador to the United States?"

He had arranged for $100,000 to be wired to the United States as a downpayment, not realizing that the supposed assassin he recruited was in fact working for the US authorities.

"In Mexico we hired a person called 'Junior' who turned out to be an FBI agent," Arbabsiar said in court, although officials say "Junior" was in fact a Drug Enforcement Administration informant, not from the FBI.

A frail looking man with a grey beard and a huge scar across one cheek, Arbabsiar was brought in and out of the courtroom in handcuffs and kept under close watch while he sat at a table with his lawyers.

The former Texas car salesman, who has a grey beard and wore a dark blue prison smock and orange undershirt, seemed nervous and stumbled repeatedly in his answers during the plea procedure.

Asked his age, he looked confused and said, "58, I think."

When Keenan pressured him to confirm clearly that he'd intended to murder the Saudi diplomat, Arbabsiar finally said: "No. Yes, yes."

Throughout, Arbabsiar alternated between casting worried looks around the courtroom and repeatedly smiling, including at the agents seated alongside the prosecutors.

In the run-up to what would have been the trial, the defendant underwent a psychological evaluation. However, defense lawyer Sabrina Shroff told the court Wednesday that nothing had been found to hold up the plea.

"We know of nothing that would address any issue," she said.

Attorney General Eric Holder said: "The disruption of this plot should serve as a reminder of the exceptional efforts of our law enforcement and intelligence agencies in protecting America against terrorist attacks."

FBI assistant director Mary Galligan said the plot in the US capital had threatened not only the ambassador but "innocent lives would have been lost and the national psyche damaged.

"Others who believe that they can carry out or even attempt to plan such brazen plots should be on notice: the FBI remains ever vigilant towards acts of terror both here and abroad," Galligan said.

Iran has strongly denied any involvement in what the United States says was a plot by the Quds Force, Iran's covert external action unit, to kill the ambassador.

In a largely symbolic vote last November, the UN General Assembly demanded that Iran cooperate with the US investigation into the plot.
