Officials says around 30 attackers were killed in the "complex and simultaneous" attacks while some 40 motorcycles and a large amount of military gear were also seized from the militants.
Twin attacks on the army in central Mali have killed six soldiers, while some 30 militants were also left dead in a fightback with help from French troops.
The attacks occurred overnight Saturday to Sunday near the border with Burkina Faso at army positions that have been targeted in the past, with a deadly offensive having begun in northern Mali in 2012 before spreading elsewhere.
"The provisional toll is six dead and 18 wounded" among the soldiers, the army said in a statement, adding that "thanks to quick reactions and effective coordination between the Malian army and French Barkhane forces, the attackers were routed" leaving around 30 dead.
It was not immediately clear what the role of the French troops in the engagement was, although a Malian military source told AFP French aircraft destroyed several "terrorist" targets.
The raids occurred at Boulkessy and Mondoro in the violence-wracked centre of the Sahel country.
The "complex and simultaneous" attacks occurred at around 3:30 am (0330 GMT), the army said, with a local official in Mondoro estimating that the fighting continued for around an hour.
Some 40 motorcycles and a large amount of military gear were seized from the attackers, according to the army.
A number of wounded soldiers were evacuated by helicopter, a medical source said.

That double attack was later claimed by the main militant alliance in the Sahel region affiliated with Al Qaeda.
On Thursday, three other Malian soldiers were killed in a bomb blast in the Mondoro area.
