The Saudis are not accused of aiding the 21-year-old Saudi Air Force second lieutenant who killed three American sailors in the December shooting, two sources said, but some are said to have connections to extremist movements, according to a person familiar with the situation.
A number are also accused of possessing child pornography, according to a defense official and the person familiar with the situation. Spokespeople for the FBI and Justice Department declined to comment. The US Navy referred CNN to the Department of Defense, which has not yet responded to a request for comment.
About a dozen Saudi trainees at the Pensacola base had been confined to their quarters as the FBI investigated the shooting as a potential terror attack, and the Pentagon initiated a review of all Saudi military trainees in the country, numbering around 850 students.
The Justice Department is expected to conclude that the Pensacola shooting was in fact an act of terrorism, according to a US official.
No co-conspirators have been charged as part of the investigation, and the Saudi government has pledged its full support.
