The bodies of the 11 Ukrainians who died when an Iranian missile shot down a passenger plane have arrived in Ukraine on Sunday for a farewell ceremony.

Popular anger swelled Monday in Iran over the accidental shootdown of a Ukrainian jetliner and the government's attempt to conceal its role in the tragedy, as online videos appeared to show security forces firing live ammunition and tear gas to disperse protests in the streets.

Canadian Prime Minister Justin Trudeau said Thursday evidence indicates an Iranian missile downed a Ukrainian jetliner late Tuesday and that the strike "may have been unintentional."
