China News Service, July 12, according to foreign media reports, Iran said that the key "human error" factor that caused the Ukrainian passenger plane to crash in Iran in January this year was the inaccuracy of the radar system of the Iranian air defense force.

On January 8, local time, the planned flight PS752 of Ukraine to Kiev crashed shortly after taking off from Khomeini International Airport in Tehran, Iran, killing all of the passengers.

  According to Agence France-Presse, the Iranian Civil Aviation Authority said in a report later on the 11th that due to human error in the radar calibration operation of the (air defense force), the radar system has deviated.

  On June 29, Iran’s military prosecutor in Tehran Province, Gram Abbas Torki, said that the reason for the Ukrainian passenger plane being shot down in Iran was "human error". Three people related to the accident have been arrested.

  In addition, Ukrainian Deputy Foreign Minister Ye Ning said on July 6 that France will begin the identification of the black box of the Ukraine International Airlines shot down passenger plane in Iran from July 20, and this work will be completed within 5 days.

  On January 8, 2020, a Boeing 737-800 airliner of Ukrainian International Airlines crashed near Khomeini International Airport in Tehran. None of the 167 passengers and 9 crew members survived.

  The Iranian military then admitted to shooting down Ukrainian passenger planes due to mistakes. The crash occurred a few hours after Iran attacked the US military base in Iraq. Iran was then expecting the United States to launch a new attack, so the air defense system was in a state of readiness. In early January, U.S.-Iranian relations deteriorated sharply as a result of a high-level Iranian commander Sulaymani killed by a U.S. military drone.
