(CNN) -- Two foreigners, including one who was a legal resident of the United States, have been charged with conspiracy to provide material support to terrorists in an indictment from Pennsylvania.
The men are linked with the activities of a woman known as "Jihad Jane" who pleaded guilty this year to conspiring to support terrorists and kill someone overseas, according to the indictment.
Ali Charaf Damache, 46, is an Algerian who resides in Ireland, where he is in prison on unrelated charges.
Mohammad Hassan Khalid, 18, is a Pakistani citizen who lived in Maryland and was arrested there in July, authorities said.
The two are accused of using the Internet to recruit for and aid a violent jihad organization that included travel to South Asia for explosives training. They both face charges of providing material support to terrorists. Damache also faces one count of attempted identity theft to facilitate an act of international terrorism.
They worked together with Colleen LaRose, alias "Jihad Jane," and an accomplice of hers, a Colorado woman named Jamie Paulin-Ramirez, the indictment says. Paulin-Ramirez pleaded guilty to providing material support to terrorists in March.
"Today's indictment, which alleges a terrorist conspiracy involving individuals around the globe who connected via the Internet -- including a teenager and two women living in America -- underscores the evolving nature of violent extremism," said Assistant Attorney General Lisa Monaco.
According to the indictment, Damache and Khalid, together with the two women, worked to provide logistical support, recruitment services, financial support and identification documents in a plot to commit murder overseas.
The indictment gives examples of communications that Damache sent under the pseudonym "Theblackflag," while Khalid used the wordy nickname "Abdul Ba'aree 'Abd Al-Rahman Al-Hassan Al-Afghani Al-Junoobi W'at-Emiratee."
"This investigation highlights the diverse threat environment we face today," said FBI Executive Assistant Director Mark Giuliano. "As revealed in this case, individuals used the Internet to further their radicalization and contribute to the radicalization of others."
The United States will seek the extradition of Damache to face trial in Pennsylvania.
The court document also revealed some personal information about the group. Damache married Paulin-Ramirez on the day she moved to Europe to live and train with jihadists, even though she had never met him in person. She moved to Europe with her son, who the couple began training "in the ways of violent jihad," the indictment says.
If convicted, Damache faces up to 45 years in prison. Khalid faces up to 15 years.
