DUBAI—Iran’s Civil Aviation Organization blamed a misalignment of a radar system and lack of communication between the air defense operator and his commanders for the accidental downing of a Ukrainian passenger plane in January that killed 176 people aboard.
Iran’s Revolutionary Guards shot down the Ukraine International Airlines flight with a ground-to-air missile on Jan. 8 shortly after the plane took off from Tehran, in what Tehran later acknowledged as a “disastrous mistake” by forces who were on high alert during a confrontation with the United States.
