More than 30 people have been killed in sporadic tribal fighting in Papua New Guinea's Enga Province over the past 3 months.
According to the Post Courier newspaper, the fights were sparked by land issues and it report that the combatants have engaged in guerrilla type tactics, using high powered weapons, including grenades.
The Provincial Police Commander Martin Lakari says since April, fighting between two factions of the Pyain tribe have led to the deaths of more than 20 people, including two men and their wives.
He says last month, two women and five men were killed during a tussle near Pilikambi High School.
Village court officials, police and a local MP have issued a prevention order against those involved in the fighting, but the hostilities appear to be continuing.
