Iran has filed a challenge at the International Court of Justice (ICJ) against Canada, Sweden, Ukraine, and Britain regarding a UN aviation body’s ruling on the 2020 downing of a Ukrainian passenger plane that killed all 176 people onboard. Iran argues that the International Civil Aviation Organization (ICAO) lacked jurisdiction over the case, asserting the incident was unintentional and due to human error amid heightened military alert due to tensions with the U.S. The four countries are seeking accountability and compensation from Iran for the victims’ families.
