Iranian missile likely shot down Boeing jet, evidence suggests: Officials

American and allied officials said on Thursday that they had intelligence that missiles fired by Iranian military forces were responsible for the downing of a Ukrainian jetliner and the deaths of all aboard this week in Iran, most likely by accident.

The disclosures suggested that the deaths were a consequence of the heightened tensions between Washington and Tehran that have played out since an American drone strike killed a top Iranian general last week.

Prime Minister Justin Trudeau of Canada, citing a preliminary review of the evidence, called for a full investigation “to be convinced beyond all doubt.” The jetliner was carrying 63 Canadians among its some 176 passengers and crew.
