According to a U.N. Panel of Experts report, Iran is illegally shipping fuel to Houthi rebels in Yemen to finance their military campaign. The fuel is loaded from Iranian ports under false documentation to avoid required U.N. inspections. Front companies are used to conceal that the true recipient of the shipments is a U.N.-sanctioned individual. The report also notes that the Houthis have evolved from importing complete or partially assembled weapons systems to importing high value components that are integrated into locally assembled systems.
