In a report Tuesday, the investigators said “the risks posed to civil aviation were not adequately identified. Neither by the state of Ukraine, nor by the operators, other states, and international organizations. Our investigation showed that all parties regarded the conflict in eastern part of Ukraine from a military perspective.” Russia in July vetoed a U.N. Security Council resolution to establish an international criminal tribunal to investigate the airliner’s destruction. However, states which had citizens killed in this flight ask justice. A separate investigation by the Dutch prosecutor’s office is charged with identifying suspects in the launching of the missile and building a case against them. The Dutch Safety Board identified an area of 320 square kilometers from which it said the missile that downed Malaysia Airlines Flight 17 and it was in rebel hands at the time. Dutch Prime Minister Mark Rutte said Tuesday that a key priority “is now tracking down and prosecuting the perpetrators.” Dutch prosecutors search now witnesses.
