Police in Papua New Guinea struggle to cope with 'revenge killings'

Police and military in Papua New Guinea are struggling to cope with tribal "revenge killings" among what authorities call "local terrorists" armed with high-powered weapons. There have been five days of brutal fighting between rival clans living near Porgera gold mine in Enga Province and there are reports of some 50 deaths, however, no official figures have been released. Hundreds of women and children have also been displaced as a result of the violence, Margot Staunton reports.
