Reuters - 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.
