Rocket parts recovered in Syria following the Assad regime’s January 22 and February 1 chlorine gas attacks indicate that the rockets' electrical insulating material was manufactured by German company Krempel GmbH. Photos show the parts imprinted with the company’s logo, product name, and the line “Made in Germany.” Krempel confirmed that it delivered the material, Pressspan PSP 3040, to two Iranian trading companies. The chlorine attacks used 107mm Iranian rockets modified to replace the conventional warhead with gas cylinders. The missiles’ markings indicate that they were produced in 2016 and came from Iran. The information comes from a joint investigation by the human rights organization STJ and the research platform Bellingcat.
