The security belt point in Al-Ar Yafa stopped these locomotives and subjected them to inspection following doubts about their content, and explosives experts were brought in, and in turn, they took a sample of the substance which turned out, according to their report, to be a substance that can be used as jet fuel for the process of launching short-range missiles after mixing them with other materials. Experts said the putschists in Sanaa were likely to use the substance to manufacture explosives and short-range rockets.
