Papua New Guinea massacre of 30 women and children is 'worst payback killing' in country's history

Warring clans target women and children after tribe leader's mother killed, police minister says

The brutal deaths of about 30 women and children in Papua New Guinea's highlands amount to the "worst payback killing" in the country's history, the police minister has said.

Bryan Kramer made the declaration after visiting Hela province, where 16 people were slaughtered by rival clansmen who the prime minister, James Marape, described as "warlords".
