New York, Sept. 3 : Lady Al Qaeda Aafia Siddiqui was carrying handwritten notes that made a reference to carrying out "mass casualty attacks" on New York city landmarks like Wall Street and the Brooklyn Bridge when she was arrested.

According to a federal indictment issued Tuesday in Manhattan Federal Court, the list also included the Empire State Building, the Statue of Liberty and Plum Island and a federal disease research facility off Long Island.

The New York Daily News said Siddiqui, 36, is scheduled to appear in court Thursday to answer charges of armed assault and attempting to kill U. S. nationals.

The feds called her arrest "the most significant capture" in the fight against terrorism in the past five years.

"Siddiqui repeatedly stated her intent and desire to kill Americans," Manhattan federal prosecutors say.

Notes in Siddiqui''s possession included references to "dirty bombs" and various ways to attack enemies, including destroying reconnaissance drones. A computer thumb drive referred to attacks by certain "cells," as well as recruitment and training.

Siddiqui lived in the U. S. from 1991 to 2002 and received degrees from MIT and Brandeis University in Waltham, Mass. She faces more than 70 years in prison.(ANI)
