  :Wikipedia doesn't rely on primary sources; in fact, it tends to give primary sources less credence than secondary sources, such as scholarly articles, reference books, and media reports. Secondary sources have reported the MNLA is predominantly Tuareg, though it has apparently formed alliances of one kind or another with both Malian Arabs (in the Timbuktu Region, particularly) and foreign Arab fighters allied with Islamist militancies like AQIM and the MOJWA (personally, I'd put the over/under on open warfare breaking out between the MNLA/secularists and the Islamists at about five days, but time will tell). The overwhelming characterization of this conflict has been that of a Tuareg rebellion against Mali, though I don't think it's clear that Azawad is intended as a Tuareg ethnic state at this point. -
