Unidentified gunmen on motorbikes attacked two villages in central Mali, killing at least 41 people in a part of the country where ethnic reprisal attacks have surged in recent months, a local mayor said on Tuesday.

The attacks on Monday evening on the villages of Yoro and Gangafani 2 compound a dire security situation in central Mali, where ethnic militias regularly slaughter civilians from rival groups and Islamist militants are also active.

The victims of Monday’s raids were mostly ethnic Dogons, said Issiaka Ganame, the mayor of Yoro, where 24 people were killed. Another 17 died in Gangafani 2.

“About 100 unidentified armed men circulating on motos all of a sudden invaded Yoro and fired on the population,” Ganame told Reuters. “Then they descended on the village of Gangafani 2, which is about 15 km (9 miles) away.”

The tit-for-tat violence in recent months has largely pitted Dogon hunters against Fulani herders. Attackers believed to be Fulani raided a Dogon village last week, killing at least 35 people. (Reuters)
