The Ukrainian International Airlines
Boeing 737-800, flying to Kiev and carrying mostly Iranians and Iranian-Canadians, crashed shortly after taking off on Wednesday from Tehran's Imam Khomeini airport.
The report by Iran's civil aviation organization cited witnesses on the ground and in a passing aircraft flying at high altitude as saying the plane was on fire while still aloft.
