LONDON - A Royal Navy sailor has been charged with murdering a fellow crew member on a British nuclear submarine, prosecutors said on Sunday.

Ryan Donovan, 22, was also charged with three counts of attempted murder following a shooting incident on Friday aboard the submarine Astute while it was berthed at the southern English port of Southampton.

"I... have authorized (the police) to charge Ryan Samuel Donovan with Ian Molyneux's murder and with the attempted murder of Christopher Brown, David McCoy, and Christopher Hodge," Nick Hawkins, chief prosecutor for the Wessex service, said in a statement.

Police and the defense ministry have said the shooting was not terrorism-related and there was no risk to the public.
