BBC: US fighter jets dropped four bombs on the Great Barrier Reef off Australia's coast during a training exercise that went wrong, it has emerged.
The two planes jettisoned four bombs - two inert and two unarmed - in more than 50m (165 ft) of water, away from coral, to minimise damage to the World Heritage Site, the US navy said.
The jets were to bomb an island range nearby, but the mission was aborted.
The AV-8B Harriers were low on fuel and could not land loaded, the navy added.
