On Friday, Iranian Foreign Ministry Spokesman Seyed Abbas Araqchi expressed regret over the prison sentence imposed by a New York court over allegations of Arbabsiar's role in a plot to kill the Saudi ambassador to the United States.
"By issuing such a verdict, the independence of the US judiciary system was once more warped in favor of political purposes," Araqchi stated
The foreign ministry spokesman also said Arbabsiar's detention conditions were inhumane, hence any confession made by the accused lacks any judicial credibility.
Late in October, Iranian Deputy Foreign Minister for Consular, Parliamentary and Expatriates' Affairs Hassan Qashqavi told FNA, "If you ask the Iranian citizens who have been imprisoned in the US, they will unanimously say that the US officials had sought to lure or intimidate them on the very first day of their detention."
He said that this method of interrogation and taking confessions under pressure is a violation of judicial laws, and stressed, "This method has been used in connection with all the Iranian prisoners (including Arbabsiar) in US jails."
The Iranian government has denied any connection to Manssor Arbabsiar, the man arrested in the alleged plot to assassinate the Saudi envoy to Washington, and derided the claims, saying US officials have offered no proof. Arbabsiar is a 56-year-old naturalized US citizen who also had an Iranian passport.
Iran has many times dismissed the US accusations that it aimed to assassinate the Saudi envoy to Washington.
