Flight training has been suspended for more than 300 Saudi Arabian students at three bases in Florida in the wake of the deadly shooting by a Saudi Air Force officer on Friday, the U.S. Navy said Tuesday.

Navy Commander Clay Doss said classroom training is going to start again this week, and flight training for other students will resume. But the Navy on Monday evening ordered that Saudi students at three bases in northern Florida be restricted from flying for an undetermined period of time.

The flight restriction affects 140 students at Pensacola Naval Air Station, where the shooting occurred, and 35 at nearby Whiting Field. Another 128 students at Naval Air Station Mayport, on the Atlantic seaboard, are also restricted.

Doss said the stand-down is an effort to ensure the safety of the students, as they recover from the trauma of the shooting, which killed three U.S. military members and injured eight other people. Police shot and killed the Saudi shooter.

A US official says the Saudi student who fatally shot three people at a Florida naval base had hosted a dinner party the night before to watch videos of mass shootings.

The official was briefed by federal investigators and spoke on the condition of anonymity. He says authorities tell him one Saudi student was recording outside the building while the shooting took place. He says 10 Saudi students are being held at the base and that several others are still unaccounted for.
