Mali's defense ministry says at least four soldiers have been killed in an attack by armed men in the central Segou region.
Defense Minister Tiena Coulibaly says the gunmen ambushed the convoy Tuesday. No group has claimed responsibility, but the attack is similar to others by al-Qaida-linked extremists in Mali's central region.
Extremist groups linked to al-Qaida and the Islamic State organization roam Mali's north and center, targeting Malian and French troops and other high-profile targets including the headquarters of a new regional counterterror force.
The attack comes as votes are counted after Sunday's elections. Provisional results are expected this week. If none of the 24 presidential candidates wins more than 50 percent, a second round will be Aug. 12.
