Residents and survivors of a massacre in a village in Burkina Faso said on Saturday that 136 people, including women and children, had been killed. A statement issued by residents and survivors on Saturday said the village was surrounded early in the morning on April 20 by heavily armed men in military uniform.

The attack sparked condemnation and calls for an investigation by the U.N. human rights office, one of the worst attacks targeting civilians in the country facing militants linked to al Qaeda and Islamic State.
