The Washington Post reports an American citizen who was once thought to be a top operative in al-Qaeda has been detained in Pakistan and secretly flown to New York to face federal terrorism charges, according to U.S. officials. Muhanad Mahmoud al Farekh, 29, was expected to be arraigned in federal court in Brooklyn on Thursday. Farekh, also known by the nom de guerre Abdullah al-Shami, was charged with supporting al-Qaeda. Pakistani forces detained Farekh several weeks ago and recently transferred him to U.S. custody after his identity was confirmed. Officials said he was questioned by members of an interrogation team composed of FBI, CIA and Pentagon officials and then advised of his Miranda rights. Little is known about Farekh, who is believed to have been born in Texas but to have moved with his family at a young age to Jordan, where he also has citizenship. Around 2007, Farekh traveled to Pakistan to link up with militants fighting U.S. troops across the border in Afghanistan, officials said, speaking on the condition of anonymity because details of the case have remained secret.
