Canada's Prime Minister Justin Trudeau said he had "impressed upon" Iran's foreign minister on Friday that a complete and independent investigation into the shooting down of a Ukrainian passenger plane in January had to be carried out.
"The promise I made to Canadians was to find answers for them and ensure that Iran leads a full investigation with the international community ... and holds to account the people responsible for this and that is my focus," Trudeau told reporters after meeting Mohammad Javad Zarif earlier on Friday.
