A tribal dispute has erupted into a gun battle at Papua New Guinea's main domestic airport, with reports of two innocent bystanders wounded.
AAP reports a disgruntled village chief, with an ammunition belt slung across his shoulder, is believed to have opened fire on a rival clansman in the Port Moresby Airport car park.
The flare-up is believed to have involved the former president of an independent landowner group and the newly-elected president, who were returning to their village in the remote Highlands region.
The warring factions come from Moran, a site in the Southern Highlands Province, where mining company Oil Search operates.
Police at the scene shot the gunman in the legs and took him to hospital where he remains under guard.
