Ukraine's deputy foreign minister told Radio Farda that the most important issue for Kyiv is to find the whole truth about the downing of its passenger plane by Iran in January.
Ukraine says those responsible for ordering missiles to be fired at its passenger plane in Iran must be punished. or Kyiv will resort to international courts.
Radio Farda has been informed that Iran is pushing Ukraine to sign a memorandum of understanding which obliges Ukraine and the families of victims of flight 725 to waive their right to pursue the matter any further through courts.
Two weeks after Iran's Revolutionary Guard acknowledged they had downed a Ukrainian airliner killing all 176 on board, Ukraine keeps insisting on its demand for transparent investigation into what happened to Flight 752.
