AFP, WASHINGTONThe US is to send home 21 Saudi Arabian military trainees after an investigation into a “jihadist” killing of three US sailors last month, the US Department of Justice announced on Monday. The Dec. 6 shooting attack by Royal Saudi Air Force Second Lieutenant Mohammed Saeed Alshamrani at Naval Air Station Pensacola in Florida was an “act of terrorism,” US Attorney General Bill Barr said. The Saudi Arabian government had vowed to review each case under its code of military justice and criminal code, he said. The shooting threatened a decades-old military training program crucial to the US-Saudi Arabian relationship, which involves billions of dollars in military sales to the kingdom. However, Senator Rick Scott called for the suspension of the Saudi Arabian program for further review by the US Department of Defense (DOD).
