Iran has rejected a Canadian court’s decision that it is liable for the shooting down of a passenger plane carrying Canadian citizens last year. 

The top court in the Canadian province of Ontario ruled Thursday that the shooting down of Ukraine International Airlines Flight PS752 was an act of terrorism by the Iranian state. The ruling allows families of the victims to seek damages from the Islamic Republic, the Canadian Broadcasting Corporation reported. 

Ukraine International Airlines Flight 752 was shot down on Jan. 8, 2020, by the Islamic Revolutionary Guard Corps shortly after taking off from Tehran. All 176 people on board died, including 55 Canadian citizens. Many of those on board were dual nationals of Iran and other states. At the time, Iranian forces were in the middle of striking US military positions in neighboring Iraq. The legal decision was the result of a lawsuit brought by some families of the victims. 

The Iranian government said the tragedy was the result of a human error, as air defense forces mistook the aircraft for a military target during the conflict with the United States. An Iranian court charged 10 people in relation to the incident in April.
