NEW YORK - An American-educated Pakistani neurosc-ientist suspected of Al-Qaeda ties has been extradited to the United States from Afghanistan to face charges with trying to kill US agents and military officers while in Afghan custody last month, the US Justice Department said. Aafia Siddiqui, who studied at Brandeis University and the Massachusetts Institute of Technology (MIT), was flown to New York from Afghanistan on Monday, and was to be arraigned later on Tuesday in the United States District Court for the Southern District of New York, the department said in a Press release. A number of reporters and cameramen have gathered outside the court, but till lunch-time there was no sign of the 36-year-old Ms Siddique nor were officials were saying when she might be brought in. A lawyer for Ms Siddiqui's family said the allegations were false. In Washington, a spokesman for the Pakistan Embassy said that a request for consular access to Ms Siddiqui has been made by Ambassador Husain Haqqani to the US authorities on Monday. Ms Siddiqui disappeared with her three US-born children while visiting her parents home in Karachi in March 2003. Leading human rights groups and her family believed that she had been secretly detained. But in a criminal complaint made public on Monday night, American officials said they had no knowledge of Ms Siddiqui whereabouts for the past five years until July 17, when she and a teenage boy were detained in Ghazni, Afghanistan, after local authorities became suspicious of their loitering outside the provincial governor's compound, according to the Press release. When they searched Ms Siddiqui's handbag, the Afghan police found documents describing the creation of explosives as well as excerpts from the Anarchist's Arsenal, it said. She also carried sealed bottles and glass jars filled with liquids and gels. The day after she was detained, an American team, including two FBI agents, two American soldiers and interpreters, came to the police station to talk to her. The FBI has wanted her for questioning since May 2004, the Justice Department said. The US complaint gave the following account of what happened next: Americans entered a room in the police station, unaware that Ms Siddiqui was being held there, unsecured, behind a curtain. One of the soldiers, a warrant officer, sat down and placed his M-4 rifle on the floor next to the curtain. Shortly after the meeting began, the other soldier, a captain, heard a woman yelling from behind the curtain. He turned to see Ms Siddiqui pointing the warrant officer's rifle at him. The interpreter sitting closest to Ms Siddiqui lunged at her and pushed the rifle away as she pulled the trigger and shouted, =E2=80=9CGod is Great. She fired at least two shots, but no one was hit. The warrant officer returned fire, hitting Ms Siddiqui at least once in the torso. Ms Siddiqui struggled when officers tried to subdue her, striking and kicking them while shouting in English that she wanted to kill Americans. She eventually lost consciousness. Ms Siddiqui was charged Monday with one count of trying to kill American officers and employees and one count of assaulting the officers and employees, the Justice Department said. If convicted, she faces a maximum sentence of 20 years in prison for each count. Meanwhile, human rights groups and the lawyer for Ms. Siddiqui, Elaine Whitfield Sharp, said they believed that Ms Siddiqui has been secretly detained since 2003, much of the time at Bagram Air Base in Afghanistan. We believe Aafia has been in custody ever since she disappeared, Ms Sharp told The New York Times by telephone, and we're not willing to believe that the discovery of Aafia in Afghanistan is coincidence. Ms Sharp also disputed the US government's earlier claims that Siddiqui had gone underground for several years before her capture. "I believe she's become a terrible embarrassment to them, but she's not a terrorist." She said her client was not an Al Qaeda terrorist, but an innocent woman who had been held at Bagram air base in Afghanistan or elsewhere for the last several years and tortured by some combination of US, Pakistani and Afghan officials. Sharp said that Ms Siddiqui had obtained an undergraduate biology degree from MIT and a doctorate in behavioral neuroscience from Brandeis University, both near Boston, and that she had lived a quiet life in the Boston area, and in Houston before that, before returning to Pakistan in late 2002. One senior US federal law enforcement official, according to The Los Angeles Times, refused to comment on the case, except to say that Siddiqui was an extremely significant catch and that authorities had pledged not to discuss any details of the operation because of its sensitivity and relationship to ongoing counter-terrorism operations. "We can't say anything about this one," said the official, who spoke on the condition of anonymity. He confirmed that the woman in custody was the one near the top of the FBI=E2=80=99s Most Wanted List of fugitive terrorism suspects wanted for questioning. Monitoring Desk adds: Elaine Whitfield Sharp, a Massachusetts attorney representing Aafia, told CNN she found a lot of the allegations against her client 'implausible' and said the charges 'don't pass the sniff test'. Her attorney said the 36-year-old neuroscientist received an undergraduate degree in biology at the Massachusetts Institute of Technology and a doctorate in behavioural neuroscience at Brandeis University - two prestigious colleges in the Boston, Massachusetts, area. "This is a very intelligent woman. What is she doing outside of the governor's residence?" Sharp said. "The woman is a PhD. Is a woman like this really that stupid? There is an incongruity, and I have trouble accepting the government's claims. "If she was carrying fluids and was considered dangerous, then why was she left unattended in a room behind a curtain? And this dangerous, hardened criminal picks up a gun and misses?" Sharp confirmed that her client had lived in Houston, Texas, and in the Boston area and returned to Pakistan in late 2002. Aafia obtained a biology degree in the US in 1995 and is reported later to have become a doctor in neurological science. The American media has reported that she is linked with Adna El Shukrijumah, another terror suspect named by the FBI. Aafia's mother said in 2003 that she had last seen her daughter in April of that year when she took a minicab from Karachi to Islamabad.
