More than 130 people were killed in an attack on a Fulani village in central Mali on Saturday, the United Nations said, as a delegation visited the country.
Survivors accused traditional Dogon hunters of carrying out the deadly raid in Ogossagou, according to Boubacar Kane, the governor of Bankass district which covers the village. A security source told AFP the victims were shot or hacked to death with machetes.
"The Secretary-General is shocked and outraged by reports that at least 134 civilians, including women and children, have been killed," Antonio Guterres's spokesman said in a statement, adding he called on Malian authorities "to swiftly investigate it and bring the perpetrators to justice".
Guterres's spokesman said the UN mission in Mali, MINUSMA, provided air support to deter further attacks and assisted with the evacuation of the injured.
The massacre took place as a delegation from the United Nations Security Council visited the Sahel region to assess the jihadist threat there.
