The United States is preparing to remove more than a dozen Saudi military students from a training program and return them to their home country after an investigation into a deadly shooting by a Saudi aviation student at a Florida navy base last month, a U.S. official told The Associated Press.

The 21-year-old Saudi Air Force officer, 2nd Lt. Mohammed Alshamrani, opened fire at the base in Pensacola, killing three U.S. sailors and injuring eight other people. The Justice Department has been investigating the incident as an act of terrorism.

Officials have said Alshamrani hosted a party before the shooting, where he and others watched videos of mass shootings. The gunman had also apparently taken to Twitter before the shooting to criticize U.S. support of Israel and accuse America of being anti-Muslim, another U.S. official told the AP last month.

Alshamrani, who was killed by a sheriff’s deputy during the rampage at a classroom building, was undergoing flight training at Pensacola, where members of foreign militaries routinely receive instruction.
