More than a dozen Saudi servicemen who are training at US military bases are set to be expelled from the country following a deadly shooting last month by a Saudi Air Force officer at an American naval base in Florida.

The Pentagon has recommended removing the Saudi personnel, though none of them are accused of aiding the Saudi Air Force second lieutenant who killed three American sailors at the Pensacola installation on December 6, CNN reported on Saturday.

The Pentagon, the Justice Department, the FBI and the Saudi Embassy in Washington did not immediately respond to requests for comment.

It follows an announcement by the the Pentagon on Dec 10 it was halting operational training of all Saudi Arabian military personnel in the US after the incident. Nine days later it announced it found no threat in its review of about 850 military students from Saudi Arabia.
