An independent report into the downing of Ukrainian Airlines flight PS752 in January 2020 has found flaws into Iran's probe into the crash, saying the country was not conducting its investigation properly and many questions remain unanswered. The plane went down after an Iranian surface-to-air missile struck the aircraft, resulting in the death of all 176 people onboard, most of whom had ties to Canada. Abigail Bimman delves into the report and the calls being made for "more credible investigations."
