The attacks took place near the town of Paoua, near the border with Chad, this week. A UN spokesperson believes a group called 3R are responsible. They are said to have called a meeting for people in the villages surrounding Paoua, but then killed those who showed up.

Sister Ines Nieves Sancho was killed nearly two weeks ago in the town of Nola in southwest CAR.

She had lived in the area for a long time and worked with impoverished women and young girls.

It has not been confirmed who carried out her beheading.

But local authorities are not linking her death with current sectarian violence between Muslim and Christian militias, according to the Washington Post.
