Witness Alassane Hamidou said at least two people were wounded in tonight's attack.
Hamidou told The Associated Press that his life was spared by the attackers because he's Muslim and they were looking for Christians.
The security official who confirmed the attack spoke on condition of anonymity because he wasn't authorized to speak to the media.
It wasn't immediately clear who was behind the violence, though neighboring Mali is home to an array of extremist groups.
