Iranian investigators on Saturday released a report blaming a misaligned missile battery and miscommunication between soldiers and their commanders for the Islamic Revolutionary Guard Corps shooting down a Ukrainian International Airlines passenger jet in January, killing 176 people. Iranian troops were on high alert for a U.S. response to an Iranian ballistic missile attack targeting U.S. soldiers at an Iraqi army base, a retaliatory act following a U.S. drone strike that killed Iranian Gen. Qassem Soleimani. The report found that while using a relocated surface-to-air missile battery that was not properly reoriented, the operator received erroneous information on the plane's trajectory, mistaking it for a missile. However, the report said the operator should have still been able to identify the plane. Those manning the missile battery were also unable to communicate with their command center and fired twice without getting approval.
