The shooting down of a Ukrainian airliner in Iran in January was due to human error and not an order from senior military authorities, the military prosecutor for Tehran province, Gholam Abbas Torki, said on Monday, Tasnim news agency reported.
There was no indication that the downing of the airliner, which killed all 176 people aboard, was due to a cyber attack on Iran's missile or air defense systems, Torki said, adding that three people were under arrest related to the accident.
