Russia has appealed to the International Civil Aviation Organization to open a new probe into last year's downing of Malaysia Airlines Flight 17 over eastern Ukraine, the chief of the Russian aviation agency said Wednesday, October 14, the Associated Press reports.

The Boeing 777 crashed on July 17, 2014, in the middle of a military conflict between Russia-backed separatists and Ukrainian government forces.

The Dutch Safety Board said in its final report released on Tuesday that the jet was destroyed by a Soviet-made Buk surface-to-air missile. Two-thirds of the 298 people who died were Dutch.

The 15-month probe did not explicitly say who had fired the missile, but it identified an area of 320 square kilometers (120 square miles) from where it said the launch must have taken place. All of the land was in the hands of pro-Russian separatists fighting Ukrainian forces at the time of the disaster, according to daily maps of fighting released by the Ukrainian National Security Council.

Russia and the rebels insist that if the plane was destroyed by a missile, it must have been fired by the Ukrainian military. "The Russian commission categorically disagrees with the conclusions of the final report. They are fundamentally wrong, the lack of logic there is beyond comparison," Oleg Storchevoi said in a televised news conference on Wednesday. "I had a feeling that the commission was cherry-picking the evidence to suit a theory they had chosen."

Storchevoi said Russia "will use its right" to continue the probe and has already appealed to the U.N.'s civil aviation agency to intervene.
