A Ukrainian airliner that crashed in Iran, killing all 176 people aboard, was likely brought down by an Iranian missile, Canada’s prime minister, Justin Trudeau, said, citing intelligence from Canadian and other sources.

“We have intelligence from multiple sources, including our allies and our own intelligence. The evidence indicates that the plane was shot down by an Iranian surface-to-air missile”, - he said.

According to Trudeau, his Government would not rest until it had obtained closure, transparency, accountability and justice.

The Ukraine International Airlines flight to Kiev from Tehran crashed on Wednesday hours after Iran fired ballistic missiles at U.S. targets in Iraq. All 176 people on board, including 63 Canadians were killed.
