Tehran: Iran has asked Canada to share any information it has regarding the Ukrainian airliner crash after Candian Prime Minister Justin Trudeau said that his country has intelligence from several sources to prove that Tehran shot down the aeroplane with 176 people onboard by surface-to-air missiles.

"[Iran] asks the Canadian prime minister and any other government to share information on this incident they possess to the committee in charge of investigating the incident in Iran," Sputnik quoted a statement by Iranian Foreign Ministry spokesman Abbas Mousavi. Mousavi added that Iran had invited Ukrainian experts as well as representatives of the Boeing company to join the investigation into causes of the crash.
