Pregnant women and children reportedly killed in Papua New Guinea tribal violence

More than 20 people including pregnant women and children have been killed in recent tribal violence in Papua New Guinea, according to media reports. The death toll and dates of the violence in the remote highland province of Hela varied in reports by Australian Broadcasting Corp and the Post-Courier newspaper.
Hela governor Philip Undialu told ABC the latest violence was on Monday when 16 people including women and children died at the village of Karida. The killings were probably retaliation for an earlier attack that left around seven dead, Mr Undialu said.
