As Iran, US Take Step Back from Brink, Canada Grieves Associated Press TORONTO - The worst had passed, it seemed, and the United States and Iran no longer appeared poised at the edge of war. "All is well!'' President Donald Trump tweeted Tuesday night, days after a U.S. drone strike killed Iran's most powerful general, and Iran, after a barrage of missiles, had signaled it was stepping back from further escalation. But 27 seconds before Trump's tweet, commercial flight trackers had lost contact with a Ukrainian International Airlines jet that had just taken off from Tehran's main airport. On board were 176 people, including 138 passengers on their way to Canada and at least 63 Canadian citizens and 11 Ukrainians. The plane, which never made a mayday call, slammed moments later into the ground. Everyone on board died. They were students, newlyweds, doctors and parents. The youngest was a 1-year-old girl, Kurdia Molani, who was flying back home with her parents to the Toronto suburb of Ajax. By late Thursday, Western leaders said that Iran had most likely shot down the jetliner with a surface-to-air missile -- probably by accident. The loss of so many lives transformed the U.S.-Iran confrontation, which had seemed to conclude with limited bloodshed. Instead, what had begun with a drone attack on Gen. Qassem Soleimani's motorcade at the Baghdad airport had suddenly rippled outward until dozens of Iranian-Canadians, dozens of Iranian students studying in Canada, were dead. "The community is overwhelmed with mourning and sadness,'' said Payman Parseyan, a prominent Iranian-Canadian in western Canada, counting through the names of the friends he had lost. .
