Mali's most radical Tuareg rebel chief Ibrahim ag Bahanga, who never agreed to disarm, died Friday in an accident in the northeast of the country and was immediately buried, his family said.

Family member Bay ag Alhassane, who broke the news to AFP, did not give details of the accident but it was confirmed by several councillors in the Kidal region.

Ibrahim ag Bahanga never totally joined in north Mali's peace process that resulted from the 2006 Algiers accords between the Malian government and Tuareg rebels.
