A US Navy F/A-18 jet accidentally dropped a bomb on a group of military personnel at a bombing range in northern Kuwait, killing six people, including five Americans and one New Zealander, Pentagon officials said. At least seven other military servicemen, five Americans and two Kuwaitis, were injured. Last month, the USS Greeneville submarine knifed into a Japanese fisheries training boat, killing nine. Six people also died in a helicopter crash during a night manoeuvre in Hawaii. Earlier this month, six National Guard officers died when their transport plane crashed over Georgia.
