A former rebel leader in northern Mali was killed in the capital Bamako on Tuesday, according to the spokesman for a militia alliance in the region.
Sidi Brahim Ould Sidati was the rotating president of the Coordination of Azawad Movements (CMA), a mostly Tuareg alliance that rose up against the central government in 2012.
The report by spokesman Almou Ag Mohamed on social media was confirmed by a doctor and a close associate of Ould Sidati.
The reason for the killing in the poor Sahel country was not immediately clear.
The accord, seen as crucial to ending Mali's grinding conflict, has yet to be fully implemented in the former French colony.
