Gunmen killed at least 110 Fulani herders in central Mali on Saturday, a local mayor said, the deadliest such attack in recent times in a region reeling from worsening ethnic violence.
The assaults on the villages of Ogossagou and Welingara took place as a U.N. Security Council mission visited Mali to try to find solutions to violence that killed hundreds of civilians last year and is spreading across West Africa's Sahel region.
Moulaye Guindo, mayor of the nearby town of Bankass, said armed men, who were dressed as traditional Donzo hunters, encircled and attacked Ogossagou at about 4 a.m. (0400 GMT).
"The body count continues by the gendarmes, who have just told me they have found 110 bodies, but the count continues," Guindo told Reuters by telephone from Ogossagou.
He said another nearby Fulani village, Welingara, had also been attacked, causing "a number" of deaths, but he did not yet know how many.
Security sources said the dead included pregnant women, children and elderly people.
One Ogossagou resident, who asked not to be identified, said the attack appeared to be in retaliation for an al Qaeda affiliate's claim of responsibility on Friday for a raid last week that killed 23 soldiers.
The group said the raid was payback for violence by Mali's army and militiamen against the Fulani.
Jihadist groups linked to al-Qaeda and Daesh have exploited ethnic rivalries in Mali and its neighbours Burkina Faso and Niger in recent years to boost recruitment and render vast swathes of territory virtually ungovernable.
French forces intervened in Mali, a former French colony, in 2013 to push back a jihadist advance from the desert north but the militants have since regrouped and expanded their presence into central Mali and the neighbouring countries.
Some 4,500 French troops remain based in the wider Sahel, most of them in Mali. The United States also has hundreds of troops in the region.
Security Council ambassadors met with Malian president Ibrahim Boubacar Keita and other government officials on Friday evening to discuss the violence.
"Clear sense of frustration among many Security Council members at pace of implementation of Mali Peace Agreement," Britain's representative on the mission, Stephen Hickey, wrote on Twitter. "Security Council prepared to impose sanctions on those who impede its implementation."
