Two men already in custody were indicted on Thursday on charges of participating in an Al Qaeda plot to detonate explosives on the New York subway system.
The two men, Adis Medunjanin, 25, and Zarein Ahmedzay, 25, were charged in a new indictment with conspiracy to use weapons of mass destruction, conspiracy to commit murder in a foreign country and providing material support for a terrorist organization.
The charges come just three days after a former high school classmate of the men, Najibullah Zazi, pleaded guilty to those same charges. Mr. Zazi, who had been the only man publicly charged with participating in the subway bombing plot, has been cooperating with federal authorities.
Mr. Medunjanin and Zarein Ahmedzay — who were arrested in January — had originally faced charges related to a trip they took with Mr. Zazi to Pakistan, where Mr. Zazi said he was recruited and trained by Al Qaeda.
They are scheduled to be arraigned on the new charges in United States District Court in Brooklyn on Thursday. They face life in prison.
While Mr. Medunjanin and Mr. Ahmedzay were before Judge Raymond J. Dearie, F.B.I. agents and police detectives from the Joint Terrorist Task Force executed a search warant at Mr. Medunjanin’s home, a law enforcement official said.
Before the new indictment, Mr. Medunjanin had been charged with conspiracy to commit murder in a foreign country and receiving military training from a terrorist organization. Mr. Ahmedzay had been charged with lying about his trip to Pakistan. Those charges remain.
While speculation as to the identity of Mr. Zazi’s co-conspirators had centered on Mr. Medunjanin and Mr. Ahmedzay, they had not been formally implicated in the domestic terrorism plot until the new indictment.
The men abandoned their attack plans in September just days before they had been planning to carry it out, after realizing they were under government surveillance. Mr. Zazi was arrested later that month.
“The facts alleged in this indictment shed further light on the scope of this attempted attack and underscore the importance of using every tool we have available to both disrupt plots against our nation and hold suspected terrorists accountable for their actions,” Attorney General Eric H. Holder Jr. said in a statement. “This attack would have been deadly, and the many agents, prosecutors and intelligence professionals who worked together seamlessly to thwart it deserve our thanks.”
