Two New York women arrested on charges of plotting to wage jihad on US soil

Two women have been arrested in New York on charges they plotted to wage violent jihad by building a homemade bomb and using it for a Boston Marathon-type attack.

One of the women, Noelle Velentzas, had been "obsessed with pressure cookers since the Boston Marathon attacks in 2013" and made jokes alluding to the explosives after receiving one as a gift, according to a criminal complaint unsealed in federal court in Brooklyn, New York.

It says in a conversation with an undercover investigator about the women's willingness to fight, she pulled a knife and asked, "Why can't we be bad b-----s?"

The complaint names Velentzas and her former roommate, Asia Siddiqui, as the targets of an undercover investigation into the thwarted homegrown terror plot.

The women, both from Queens, were held without bail after a brief court appearance where they spoke only to say they understood the charges against them.

"My client will enter a plea of not guilty, if and when there is an indictment. I know it's a serious case, but we're going to fight it out in court," said Siddiqui's lawyer, Thomas Dunn. Velentzas' attorney had no comment.
