Reports: US Officials Believe Iranian Missile Brought Down Ukrainian Plane VOA News U.S. media reports say American intelligence officials believe it is likely an Ukrainian passenger jet that crashed shortly after taking off from Tehran was brought down by an Iranian anti-aircraft missile. Details are still coming in. "Somebody could have made a mistake on the other side," President Donald Trump said when asked about the crash Thursday, noting the plane was flying in a "pretty rough neighborhood." Iranian investigators said Thursday the crew of a Ukrainian passenger jet had tried to turn back after takeoff early Wednesday and that the pilot made no radio communications about any problems. The initial report from iran's Civil Aviation Organization also cited witnesses on the ground and in a passing aircraft as saying the Ukraine International Airlines plane was on fire before it hit the ground. Ukrainian President Volodymyr Zelenskiy declared Thursday a day of mourning for the 167 passengers and nine crew members who died when the plane bound for Kyiv crashed early Wednesday. Ukrainian Foreign Minister Vadym Prystaiko said the dead included 82 Iranians and 63 Canadians along with Ukrainians, Swedes, Afghans, Germans and Britons. .
