"The IRGC commanders travelled there to support Houthi operations and provide training on new missile systems," one of the sources said, adding that Iran also sent gold on the aircraft to fund Houthi activities. The two Iranian sources spoke on condition of anonymity because of security concerns. ‌On July 13, the four sources said, the aircraft returned to Yemen carrying members of the delegation as well as the IRGC commanders and advisers.
