“More than 100 houses have been razed by fire since the fighting started late last month", Singura said, as quoted by The National newspaper, adding that seven people were killed in the clash.
The police deployed 15-strong mobile squad to monitor the situation on the ground, Singura noted.
“The situation now is quiet but very tense", Singura added.
According to the newspaper, the clash started from a family row, which was later joined by relatives and other people.
Papua New Guinea is considered to be one of the most diverse countries in the world, with a very high level of ethnolinguistic fragmentation among local communities, which fosters inter-ethnic violence.
