A federal grand jury has returned a three-count indictment against a Saudi national, Naif Abdulaziz M. Alfallaj (right), after his fingerprints showed upon documents found by the U.S. military at an al Qaeda terrorist safe house in Afghanistan. The same man was confirmed to have fraudulently attended flight school in Oklahoma where he was issued a private pilot’s license in Nov. 2016.

NY Times (via DML On Tuesday, the Federal Bureau of Investigation arrested a Saudi illegal migrant who attended Al Qaeda’s most notorious training camp and had been living in Oklahoma for years. Naif Abdulaziz M. Alfallaj, 34, was charged with lying to the F.B.I. and with two counts of visa fraud in Oklahoma, The New York Times reported

Alfallaj was recently discovered by the FBI when federal law enforcement officials matched his fingerprints to those taken from a document recovered by the U.S. military from a safe house in Afghanistan in December 2001. The document was a five-page application to attend the al Farooq terrorist training camp near Kandahar, Afghanistan, where trainees learn to use weapons and explosives. Four of the hijackers who perpetrated the Sept. 11 attacks trained at the Farooq camp.

The officials contended that anyone who attempted to join the camp would have had knowledge that Al Qaeda was a terrorist organization. The emergency contact listed on the document was Alfallaj’s father who lived in Saudi Arabia.

Federal court records revealed that Alfallaj, who is from Riyadh, used a fraudulent visa to take private flying lessons in October 2016 in Oklahoma. As part of the licensing process, noncitizens are required to submit fingerprints. Alfallaj’s fingerprints led the FBI to him. Following his discovery, the Federal Aviation Administration revoked Alfallaj’s flying license.

Alfallaj came to the United States in late 2011 on a nonimmigrant visa based on his wife’s status as a foreign student and resided in Weatherford, Okla., approximately 70 miles west of Oklahoma City.

Prosecutors said that Alfallaj included false answers to questions on his visa application, most notably to the question regarding whether he had supported terrorists. When FBI agents interviewed Alfallaj in December, he also lied about having contacts with members of a terrorist group. In January, Alfallaj confirmed to the bureau that the telephone number on his application to the Farooq camp belonged to his father.
