Ukraine embassy in Iran drops reference to engine failure as cause of plane crash

Ukraine's embassy in Iran dropped an initial reference to engine failure as the cause of a Ukrainian plane crash outside Tehran on Wednesday. It said in a second statement that the causes had not been disclosed and that any previous comments were not official.

Asked at a briefing in Kyiv if the plane could have been downed by a missile, Ukraine's Prime Minister Oleksiy Honcharuk cautioned against speculation until the results of an investigation were known. He also said that Ukraine had banned flights through Iranian airspace by its airliners from Jan. 9.
