There's been more upheaval at the Manhattan trial of a U.S.-trained Pakistani scientist linked to Al Qaeda.

The judge had Aafia Siddiqui removed from the courtroom Monday after she began ranting about the proceedings. Two jurors were removed shortly afterward for unclear reasons and will be replaced by alternates.

Authorities say the 37-year-old Siddiqui was caught in Afghanistan in 2008 carrying notes on bomb-making and a list of landmarks including the Statue of Liberty.

She's accused of picking up an unattended rifle and shooting at Americans who were trying to interview her.

Siddiqui is not facing terrorism charges and denies wrongdoing.
