Mother Jones magazine travels with Chadian rebels in Sudan and explores where all their guns come from:
…I saw the gun again the following day as I sat in the inner sanctum of the rebel leadership, lounging on a faux Arabian carpet in a mango grove. Various commanders passed the Glock around. From what I could discern it was a gift to Nour. I had already elicited his fury by asking uncomfortable questions about his past (he said he was a freelance oil consultant), the Darfur genocide (“a tribal matter”), and where his weapons came from (“friends”). Asking him about the Glock was a chance I did not dare take.
I spent three days in the camp, surreptitiously photographing and copying the serial numbers off of rifles, rpgs, and heavier artillery. Upon returning to Khartoum, I asked G how much it costs to supply a small rebel army: “A million dollars?” He laughed. “Less! Much, much less.”
I sent my photos and serial numbers to arms experts in Europe. The Beretta was traced to Iraq; the Glock was traced to a factory in Austria. The rest were traced to factories in China, including a grenade launcher that went into production in 2003, as the killing in Darfur flared. The UN forbids arms shipments to Darfur; however, there is no prohibition on selling weapons to the Sudanese government.
