Two U.S. two AV-8B Harrier jets accidentally bombed Australia's Great Barrier Reef during a training exercise on Tuesday, the Associated Press reported.


The jets launched from USS Bonhomme Richard and accidentally released an inert bomb and an unarmed explosive bomb from 164 feet above the water, according to a statement released from U.S. 7th Fleet on Saturday. Neither of the bombs exploded and they possibly caused minimal damage to the reef.

The incident happened during three weeks of training exercises conducted with U.S. and Australian military forces that include about 28,000 troops.
