Police in Papua New Guinea's capital have used tear gas and fired shots in the air to clear a crowd of angry land owners.
There were rowdy scenes outside the building that houses the Prime Minister's department in Port Moresby.
Hundreds of land owners from PNG's Southern Highlands gathered there demanding the government pay them millions of dollars in outstanding grants.
