Mali's Defense Ministry and a witness say three people have been killed in the central Mopti region by armed men attacking a customs post.

Col. Diarran Kone, spokesman for Mali's Defense Ministry, said Thursday that two civilians and a customs officer died in the attack in Hombori. Mouaouloud Dao, a Hombori resident, said armed men in a 4x4 vehicle came early Thursday to the post and set fire to a car before leaving.

Three soldiers were killed in the same region Tuesday after driving over a land mine.

No group has claimed responsibility for the attacks.

The Mopti region is known to be a stronghold for the Macina Liberation Front, an Islamic extremist group that claimed responsibility for several attacks on the army last year.
