Washington ? Federal prosecutors filed terrorism charges Friday against a pregnant American woman in the so-called Jihad Jane case. The two American women are accused of plotting online to attend a terror training camp.

Jamie Paulin-Ramirez flew Friday from Ireland to Philadelphia, where she was arrested by agents with the joint terrorism task force there. Her 6-year-old son flew with her and was placed in the custody of child protective service workers.

Last month, authorities in Ireland detained Paulin-Ramirez, originally from Colorado, and six others as they investigated an alleged plot to kill a Swedish cartoonist whose drawing had offended many Muslims.

Those seven suspects in Ireland were linked to Colleen LaRose, a 46-year-old woman who had traveled to Europe but was arrested last fall when she returned to the United States.
