BAMAKO, Mali — At least 31 people were killed on Friday in an attack on a village that was the scene last year of Mali’s worst civilian massacre in recent memory, the government said.

A government statement did not say who carried out the early-morning attack on Ogossagou, a village of Fulani herders in central Mali.

Last March, men believed to belong to a rival group’s militia killed more than 150 civilians in Ogossagou, an attack that highlighted the rising ethnic and jihadi violence in West Africa’s vast Sahel region.
