Ukraine has rejected the Civil Aviation Organisation of Iran's final report on the downing of a Ukrainian jet as a "cynical attempt" to conceal the truth
Ukraine International Airlines flight PS752 was hit by two missiles after taking off from Tehran on 8 January 2020. All 176 people on board died.
The report blames errors by an air defence unit for the tragedy.
It says an operator "misidentified" the plane as hostile and fired the missiles without authorisation from a commander.
