MOSCOW: The Kremlin rejected on Tuesday the “biased conclusions” of a United Nations aviation agency report, which found Russia responsible for the downing of Malaysian Airlines flight MH17 over Ukraine in 2014.The airliner was en route from Amsterdam to Kuala Lumpur when it was hit by a Russian-made BUK surface to air missile over Ukraine’s eastern region of Donetsk, where pro-Russian separatist rebels were battling Ukrainian forces.The International Civil Aviation Organization (ICAO), based in Montreal, ruled on Monday that Moscow had “failed to uphold its obligations under international air law”.“Russia was not a country that participated in the investigation of this incident. Therefore we no not accept all these biased conclusions,” the Kremlin’s spokesman Dmitry Peskov told reporters on Tuesday.Russia has always denied responsibility for the mid-air destruction of flight MH17, which killed all 298 people on board.Dutch nationals account for two-thirds of the dead. There were also 30 Australians and 30 Malaysians. Many victims had dual nationalities.
