Aircrew based at RAF Benson in south Oxfordshire have been named as missing, presumed dead, after a helicopter crash in Iraq at the weekend.

Wing Commander John Coxen and Flight Lieutenant Sarah Mulvihill were both in a Lynx helicopter that crashed in Basra on Saturday.

British investigators are examining the wreckage to see if it was shot down, as some reports have suggested.

Three other men missing were British personnel from Royal Naval Air Station at Yeovilton, in Somerset.
