The U.N. peacekeeping chief says his department is investigating what appears to be the shooting of protesters by Malian soldiers.

Herve Lasdous said Friday that one of the three people wounded died over the weekend.

Ladsous says if proven beyond a doubt that Malian soldiers did shoot, that is "absolutely unacceptable."

Residents of the troubled northern city of Kidal have said soldiers fired on a demonstration at the local airfield Nov. 28. The demonstrators had gathered to protest the arrival of Prime Minister Oumar Tatam Ly on an official visit.

Ladsous says U.N. police and French troops had ordered the crowd to disperse.

Northern Mali was taken over by al-Qaida-aligned rebels following a March 2012 military coup. France launched a military intervention in January to drive them out.
