Amnesty International's 44-page report found that much of IS’s equipment and munitions comes from stockpiles captured from the U.S.-allied Iraqi military or designed and produced in 20 countries including Belgium, Russia, China, the US and some European countries. Patrick Wilcken, researcher on Arms Control said it was essential to have careful and long-term analysis to risk assessment and measures to limit weapon export to unstable regions. He stressed that countries should draw lessons from past failures and take drastic measures to prevent proliferation of weapons in Iraq, Syria and countries in conflict areas.
