Army spokesman Col Diarran Kone confirmed the attack in the Timbuktu region and said the bodies of 17 assailants remained at the scene. The base was again under the control of the Malian military, he said.
Mali recently marked the five-year anniversary of a French military mission to oust Islamic extremists from power in the major towns of the north. That operation, however, merely dispersed the jihadists into the surrounding desert.
Last January, at least 54 people died in the eastern city of Gao in the bombing of a camp that housed hundreds of former fighters from armed groups.
The former fighters, who were signatories to Mali's 2015 peace agreement, had agreed to join forces with the military in battling extremist groups in Mali's north.
