NEW YORK ¨C U.S. authorities charged three people with terrorism-related crimes, including two New York women who allegedly discussed making bombs. A Texas man was charged separately with trying to train alongside Muslim militants.

A criminal complaint against Noelle Velentzas, 28, and Asia Siddiqui, 31, was unsealed Thursday in Brooklyn federal court, accusing the women of conspiring to prepare an explosive device to detonate in the U.S. Muhanad Mahmoud al Farekh was charged with conspiracy to provide material support to terrorists.

¡°We remain firm in our resolve to hold accountable anyone who would seek to terrorize the American people, whether by traveling abroad to commit attacks overseas or by plotting here at home,¡± U.S. Attorney Loretta Lynch said in a statement.

All three defendants were expected to appear in Brooklyn federal court Thursday.

Prosecutors said the women, U.S. citizens and onetime roommates in the borough of Queens, discussed violent jihadi views with an undercover officer and, as recently as last year, began researching and discussing plans for an attack in a self-proclaimed effort to ¡°make history.¡±

Velentzas praised the Sept. 11, 2001, attacks and the 2013 Boston Marathon bombing, and declared that she and Siddiqui were ¡°citizens of the Islamic State,¡± prosecutors said. Siddiqui had repeated contact with members of al-Qaida in the Arabian Peninsula, including Internet propagandist Samir Khan, according to the government.

In discussions with the undercover officer last year, the women said they were learning ¡°science¡± in order to build a bomb, prosecutors said. They later said they were reading technical books and learning about making homemade grenades, pipe bombs and pressure-cooker bombs, the U.S. alleged.

Velentzas discussed using the ¡°dark Internet¡± and prepaid phones to help carry out a scheme, and made trips with a group to a Home Depot to examine possible bomb-making items, prosecutors said.

She also made references to ¡°The Anarchist Cookbook,¡± which contains instructions for making explosives, prosecutors said. The bomb-making discussions continued into this year, prosecutors said.

Farekh, who studied at the University of Manitoba in Winnipeg, is accused of leaving the school in 2007 with others for Pakistan with the intention of training for violent jihad against U.S. military personnel operating in Afghanistan. He was eventually deported from Pakistan.

A purported co-conspirator, Ferid Imam, is alleged to have aided a plot to attack the New York City subways. That plot was foiled in 2009.

The cases are U.S. v. Velentzas, 15-mj-00303, and USA v. AL Farekh,1:15-mj-00021, U.S. District Court, Eastern District of New York (Brooklyn).
