On Thursday multiple news agencies reported that Ukraine International Airlines Flight 752, which crashed outside Tehran on Wednesday with 176 people onboard including many Canadians, was mistakenly shot down by Iranian forces during their missile bombardment of American forces in Iraq. Newsweek broke the story, citing a Pentagon official, a senior U.S. intelligence official and an Iraqi intelligence official. Iran is denying the reports, saying it's simply not possible that one of their surface-to-air missiles could have downed the airliner. Andrew Rasiulis is an expert on conventional warfare who served as an analyst with the Department of National Defence and as the Department of National Defence representative on NATO's High Level Task Force for conventional arms control. He joins Gormley to discuss how the Iranians may have accidentally shot down a civilian airliner, and what might happen in the aftermath.
