(CN) - A Texas man accused of conspiring to kill United States citizens at a military base in Afghanistan in January 2009 now faces additional charges, the FBI announced Wednesday.
The superseding indictment unsealed Wednesday charges Muhanad Mahmoud Al Farekh with conspiracy to murder U.S. nationals, use of explosives, conspiracy to use a weapon of mass destruction, and conspiracy to bomb a government facility.
The government accused Farekh of helping to outfit two vehicles with improvised explosive devices. Those vehicles were later driven onto the base, where one device was detonated.
Investigator said they later found Farekh's fingerprints on the device that didn't detonate.
Farekh, who is scheduled to be arraigned in Brooklyn Federal Court on Thursday before U.S. District Judge Brian Cogan, was previously charged with attempting to provide material support to terrorists.
In the original indictment lodged against him, on May 28, 2015, the government claimed Farekh traveled to Pakistan to train with al-Qaida to kill American soldiers in the Middle East.
Farekh was deported from Pakistan to the United States before he could carry out his plans, and it was there that he was arrested and later secretly flown to the United States to face charges.
Farekh pleaded not guilty to the original charges, which were rolled into the latest indictment against him.
If convicted on all charges he could face life in prison.
