A dispute over money within a Nigerian jihadist faction affiliated to the
Islamic State group has spiralled into clashes that has killed "scores" of fighters, sources said.
The infighting -- which erupted into gun battles on July 26 -- has exposed divisions inside the Islamic State West Africa Province (ISWAP) group, three sources with deep knowledge of the faction's internal workings told AFP.
The disagreement centred on sharing income mainly generated by taxing cattle herders and fishermen in areas the jihadists control around Lake Chad, said the sources, who asked not to be identified for safety reasons.
