The Woman ISIS Wanted in Exchange for Journalist James Foley

Before executing American journalist James Foley, Islamic State militants made two demands in exchange for the captive's release. They demanded a $132 million ransom and the release of Aafia Siddiqui, who's also known as "Lady of al-Qaeda".

Aafia Siddiqui is a Pakistani woman who was sentenced 86 years prison after she was found guilty of attempted murder, armed assault, using a firearm and assaulting U.S. officers.

Mother of three, 44-year-old Siddiqui is an MIT-educated neuroscientist who had lived in the US for almost a decade.

Siddiqui, who is divorced from her first husband, is said to be married to Ammar al-Baluchi, one of the 9/11 masterminds, who is currently being held in Guantanamo. He is the nephew of Khalid Sheikh Mohammed.

In 2004, she was listed on FBI's Most Wanted Terrorist list. She was arrested in 2008 by the Afghani police for a "suspicious act" near an Afghan state institution.

The police found numerous documents in her possession describing the making of explosives, chemical weapons and dirty bombs, as well as notes referring to mass attacks on various landmarks in the United States such as the building of "Empire State" in New York, Wall Street, and Brooklyn Bridge.

When U.S. investigators were questioning her, Siddiqui grabbed a rifle and opened fire in an attempt to kill them. She was consequently charged for assault with a deadly weapon and attempting to kill US personnel.

During trials, she used to interrupt attorneys and judges with fiery screams. Her lawyers had argued that she was mentally unstable.

Today, Siddiqui is being held at the Federal Medical Center, Carswell, a federal prison in Ft. Worth, Texas, that houses female inmates with mental health needs.
