Alleged al-Qaeda member Aafia Siddiqui vanishes in Karachi, Pakistan, with her three children. Although she and her family are Pakistani, she had been a long-time US resident until late 2002, and had even graduated with a biology degree from the Massachusetts Institute of Technology (MIT). The day after her disappearance, local newspapers will report that an unnamed woman has been taken into custody on terrorism charges, which is unusual since nearly all terrorism suspects have been men. A Pakistan interior ministry spokesman confirms that Siddiqui is the woman who has been arrested. But several days later, both the Pakistan government and the FBI publicly deny that she is being held. Later in 2003, her mother will claim that two days after her disappearance, “a man wearing a motor-bike helmet” arrives at the Siddiqui home in Karachi, and without taking off his helmet, says that she should keep quiet if she ever wants to see her daughter and grandchildren again. Beginning with a Newsweek article in June 2003, Siddiqui and her husband will be accused of having helped al-Qaeda as possible US sleeper agents. Siddiqui’s sister will claim that in 2004 she is told by Pakistan’s interior minister that Siddiqui has been released and will return home shortly. Also in 2004, FBI Director Robert Mueller will announce at a press conference that Siddiqui is wanted for questioning. Siddiqui divorced her long-time husband in 2002. The BBC will later report that, shortly before her disappearance, she married Ali Abdul Aziz Ali, a nephew of 9/11 mastermind Khalid Shaikh Mohammed, and alleged participant in the 9/11 plot. “Although her family denies this, the BBC has been able to confirm it from security sources and Khalid Shaikh Mohammed’s family.” In July 2008, she will reappear in mysterious circumstances in Afghanistan, and then be transferred to the US to stand trial for murder (see July 17, 2008). Allegations continue that she was secretly held by the US or Pakistan some or all of the five years between 2003 and 2008. Her three children will not be seen following their disappearance.
