Today marks five years since the downing of Ukraine International Airlines Flight 752 (Flight PS752), a sombre commemoration of indefensible actions. Fifty-five Canadian citizens and 30 Canadian permanent residents were among the 176 people killed in this tragedy. Canada and its partners in the International Coordination and Response Group— Sweden, Ukraine and the United Kingdom—continue to call on the Islamic Republic of Iran to take full responsibility for its actions, including by making reparation for the harm caused by the downing.
