Irans sentencing of 10 alleged perpetrators in the downing of a Ukrainian airliner was criticized Tuesday by Canada and other countries whose citizens were aboard the flight, saying the "sham trials" lacked impartiality and transparency. The Iranian Revolutionary Guards Corps (IRGC) shot down Ukraine International Airlines flight PS752 shortly after its takeoff from Tehran on January 8, 2020, killing all 176 people on board. Most were Iranians and Canadians, including many dual nationals. Tehran on Sunday sentenced 10 members of the armed forces, including a commander, to prison after finding them guilty of involvement in the planes downing. But in a joint statement, a coordination group representing Canada, Sweden, the UK, and Ukraine said the verdicts “must not distract the world from Irans failure to meet its international obligations and take responsibility for its actions,” according to AFP. “Neither the trials nor the verdicts announced this week brings truth or justice to the families of the victims, as the entire process - starting with Irans biased investigation into the downing - lacked the necessary impartiality and transparency,” it added. The statement noted that the families of the 176 victims were "still waiting for the justice they deserve". "We continue to stand in solidarity with the families and loved ones of the victims of the downing of Flight PS752 and will not rest until justice has been served," it concluded. Three days after the plane was shot down, Amirali Hajizadeh, the head of the Revolutionary Guards aerospace force, admitted his forces responsibility for the incident. The IRGC admitted there had been a “mistake” after mistaking the plane for an American cruise missile. The incident occurred hours after launching ballistic missiles on Ain al-Asad air base in Iraq in retaliation for the killing of the commander of the al-Quds Force, Qassem Soleimani. The Iranian judiciarys Mizan Online website reported Sunday that the commander received the heaviest penalty of 10 years in prison for having defied orders in shooting down the plane. Nine other personnel were sentenced to between one and three years, it reported. The commander of a Tor-M1 surface-to-air missile system "fired two missiles" at the airliner "contrary to orders" and without obtaining authorization, Mizan said. It did not identify any of the accused. “Given the extent of the effects and consequences of this action, the main defendant was sentenced to the maximum penalty,” Mizan Online added, without giving further details. The Association of Families of Flight PS752 Victims released a statement saying the victims’ families “never recognized the Islamic Regime’s court as a legitimate tribunal.” Victims families rejected the verdicts as “meaningless and unacceptable”, adding that the tribunal prosecuted only low-ranking officers.
