Ukraine International Airlines said on Saturday that its plane that was downed in Iran had received no warning from Tehran airport about a possible threat before it took off.
At a briefing by its president and vice president, the airline also denied suggestions that the passenger plane had veered off its normal course, and said that the Iranian authorities should have closed the airport.
The airline’s top officials also called on Iran to take full responsibility for the crash, which killed all 176 aboard.
Ukraine International Airlines's vice president said the company has changed its routes and no longer flies over Iran.
The chief of the airlines, Yevhenii Dykhne had said earlier that he never doubted that the airline had not caused the crash of its passenger plane in Iran.
Eleven Ukrainians, including nine crew members, died in the plane crash on Wednesday, according to Ukrainian government figures. Dykhne wrote a statement on social media after Iran said it had mistakenly shot down the plane.
“We didn’t doubt for a second that our crew and our plane couldn’t be the cause for this horrible plane crash,” Dykhne said.
“These were our best guys and girls. The best,” he said.
