The AV-8B Harriers, part of the 31st Marine Expeditionary Unit, had been taking part in a training exercise when the pilots realized they were running low on fuel.
Each Harrier was forced to drop two bombs on the UNESCO world heritage site, although there was no risk of them exploding, according to defense officials.
Of course you know this means war!
