Anger as US 'bombs' Great Barrier Reef

Environmentalists have expressed anger after it emerged that two US fighter jets dropped four unarmed bombs into Australia's Great Barrier Reef Marine Park when a training exercise went wrong.

The two AV-8B Harrier jets launched from the amphibious assault ship USS Bonhomme Richard each jettisoned an inert practice bomb and an unarmed laser-guided explosive bomb into the World Heritage-listed marine park off the coast of Queensland state last Tuesday, the US 7th Fleet said.
