The base is in the village of Dioura, the mayor of the nearest town Kareri, Youssouf Coulibaly, told Reuters by telephone from inside the base on Sunday.
“I’m currently inside the base and there were many deaths here. We have counted 16 so far,” Coulibalysaid. Army spokesman Colonel Diarran Kone confirmed the attack but gave no further details.

A foreign security source said efforts were under way to determine how many people had died.
Central Mali has in the past few years been overrun by fighters with links toal-Qaeda.
Growing numbers of attacks
Violence by fighter groups has worsened almost every year since it first started in Mali in 2012 when rebel fighters and allied Tuareg rebels took over the north and advanced towards the capital Bamako, until a French-led intervention pushed them back the following year.
Groups linked to al-Qaeda and the Islamic State of Iraq and the Levant (ISILor ISIS) used central and northern Mali as a launch pad for growing numbers of attacks across the Sahel region, especially on neighboursNigerandBurkina Faso, despite the presence of 4,500 French troops, UN peacekeepers, a strong French military contingent and the creation of a five-nation military force in the region.
Violence has not abated in Mali which suffered 237 attacks in 2018, UN figures show.
Central Mali is the locus of the Macina Liberation Front, led by preacher Amadou Koufa.
French Armed Forces Minister Florence Parlyclaimed in Novemberthat Koufa had been killed in a raid by French forces.
But at the end of last month, Koufa appeared in a new propaganda video mocking French and Malian forces.
