U.S. Officials Say It’s ‘Highly Likely’ Iranian Missile Downed Ukrainian Plane (Source Time) U.S. and Canadian officials have said it is “highly likely” that an antiaircraft missile strike caused the crash of a Ukraine International Airlines operated Boeing 737 in Iran on Wednesday, killing all 176 people on board. Two U.S. officials, anonymously citing U.S. intelligence, told the Associated Press that it’s possible the aircraft was mistaken as a threat and then struck by Iran. Canadian Prime Minister Justin Trudeau told reporters Thursday that intelligence from multiple sources shows the plane was shot down. At least 63 Canadians were on the aircraft. “The evidence indicates that the plane was shot down by an Iranian surface-to-air missile,” Trudeau said.  President Donald Trump dismissed Iran’s initial explanation that a mechanical error caused the crash while speaking at the White House earlier on Thursday, though he did not directly blame Iran for the crash. “It was flying in a pretty rough neighborhood, and somebody could have made a mistake,” Trump said. “Some people say it was mechanical. I personally don’t think that’s even a question.” The comments from intelligence officials, Trudeau and Trump come after Ukrainian officials said Thursday that they are considering a missile strike as one of many possible reasons for the crash. Oleksiy Danilov, secretary of Ukraine’s Security Council, told Ukranian media that officials had not ruled out a strike, the AP reported.
