" More than 20 people including pregnant women and children have reportedly been killed in tribal violence in Papua New Guinea.
Papua New Guinea's Prime Minister James Marape said those responsible for the fatal attacks could face the death penalty, warning the perpetrators “I’m coming for you”.
“Today is one of the saddest day of my life, many children and mothers innocently murdered in Munima and Karida villages of my electorate by Haguai, Liwi and OKiru gunmen,” Marape said in a statement on his Facebook page on Wednesday."
