A new report by Conflict Armament Research (CAR) claims nearly a quarter of arms recovered from Islamic State (also known as ISIS or ISIL) in Iraq and Syria were made in Romania, Bulgaria and Hungary.

The Islamist militants took the weapons from Syrian rebels and other groups who oppose them, whom bought the weapons from United States and Saudi Arabia (both The United States and Saudi Arabia supplied most of this materiel without authorisation, the report claims).

“CAR has traced numerous items deployed by IS forces to initial exports from Bulgaria to Saudi Arabia. These transfers were uniformly subject to non-retransfer clauses concluded between Saudi Arabia and the Government of Bulgaria prior to export. In this respect onward re-transfers by Saudi Arabia of these weapons contravene its commitments to the Government of Bulgaria not to re-export the material in question without Bulgaria’s prior consent”, it wrote on the report.

The 222 pages report shows 33 percent of ISIS’ weapons come from the EU-bloc, following Russia and China, which combined together provided over 50 percent of ISIS’ weapons.

The United States manufactured only 2 per cent of weapons used from IS forces and documented by CAR in the region.

Furthermore, China, Russia and Eastern European states provided around 90 percent of ammunition used by ISIS militants during their fight.
