A fascinating biography, context and details on 'The Chameleon':
Since the seizure of northern Mali during 2012 the Malian jihadist figure Oumar Ould Hamaha has emerged from the often formless haze of rarely glimpsed AQIM kidnap groups operating in the Sahel region.

(It ends)..Despite the apparent fractures between AQIM, MOJWA, Belmokhtar and others, the case study of Oumar Ould Hamaha suggests that factional politics and rivalries is unlikely to alter the practical relationships on the ground of the jihadist elements in the Sahel region that have operated together in various guises for years.
