Is Iran supplying these scum as well?
Probably- Mali is next to uranium-rich Niger.
Pakistani “Islamic bomb” scientist Qadeer Khan’s wife owned or owns a hotel in Mali’s Timbuktu.
Qadeer Khan was known to fly in there and stay.
Probably not at present, but stockpiles of arms have been emanating from the mullahcracy for decades.
Contrary to pro-mullah talking points, Iran's regime has supported Sunni as well as Shiite jihadists.
Of course, the very personality-based jihadist groups have very fluid alliance systems, giving them a fragmented structure. The IRGC happens to control all the levers of national power in Iran.
The AK-47 has been manufactured by lots of despotic regimes, and there's something north of 200 million of them on the Earth. Ammo is available by the crap-ton.
