Iranian investigators are blaming a misaligned missile battery and miscommunication between soldiers and their commanders for the Revolutionary Guard shooting down a Ukrainian jetliner in January, killing 176 people.
The report released late Saturday by Iran's Civil Aviation Organization comes months after the Jan. 8 crash near Tehran, which authorities for days denied having hand in.
The shootdown happened the same night Iran launched a ballistic missile attack targeting U.S. soldiers in Iraq, its response to the American drone strike that killed Guard Gen. Qassem Soleimani in Baghdad.
