The Us has dumped bombs near Australia's Great Barrier Reef. It was not intentional. Two of their Marine aircraft were in fuel trouble and had to jettison the dangerous cargo for safety reasons.
Before dumping the explosive devices they were disarmed. The planes were operating from a Navy ship. The now harmless bombs are sitting in a deep channel away from the Barrier Reef. They are in the Great Barrier Reef World Heritage area, however.
Plans are under way to retrieve the bombs. Just how this is to be done is unknown at present. It is not an international incident. The Australian government knows full well the immediacy of the action. There has been no protest. Removal will be done as soon as practicable.
