A young mother was burned alive in Papua New Guinea this week after townspeople accused her of being a witch.

According to multiple reports, Kepari Leniata, 20, was tortured and killed in front of a mob of hundreds in the town of Mount Hagen. The woman, stripped naked and covered in gasoline, was burned alive on a pile of trash by relatives of a young boy who had died earlier in the week. The relatives had accused Leniata of killing him with sorcery.

Police and firefighters who tried to save Leniata were chased away by an overwhelming crowd. Agence France-Press writes that the woman "admitted to killing the boy, who died after being [hospitalized] with stomach and chest pains on Tuesday."

According to the BBC, police chief Supt Kaiglo Ambane told local media that those responsible for Leniata's murder would be brought to justice.

The U.S. Embassy and Australia's high commissioner have condemned the murder. In a statement featured in a report by the Australian Associated Press, Papua New Guinea Prime Minister Peter O'Neill said that "no one commits such a despicable act."

"Barbaric killings connected with alleged sorcery. Violence against women because of this belief that sorcery kills," O'Neill said, according to the AAP. "These are becoming all too common in certain parts of the country. It is reprehensible that women, the old and the weak in our society should be targeted for alleged sorcery or wrongs that they actually have nothing to do with."

AFP notes that many people in the island nation believe in sorcery rather than accept natural causes of death. While the 1971 Sorcery Act technically outlaws the burning of alleged witches, the practice persists. In 2009, another woman was burned alive for alleged sorcery, the news outlet points out.
