The head of the Iranian Civil Aviation Organization confirmed that the Ukrainian plane that crashed in Iran was not hit by a missile, calling for not to anticipate the results of the plane's black box analysis.

Ali Abedzadeh said at a press conference held today, Friday, that the pilot of the plane contacted the control tower and asked to return to Tehran airport after take off, but he did not do it for reasons that are still unknown.

Zadeh asked the Americans "if they have proof that the plane was shot down with a missile that they can provide it," considering that talking about the plane crashing with a missile is a political rather than a technical issue, explaining that he asked for help from countries in the investigation, including Sweden and Canada.

The Iranian Civil Aviation Organization stated that the plane's black box suffered from a malfunction, but could benefit from it, noting that a fire broke out for two minutes in the plane before it crashed.

For his part, the Ukrainian President said that the hypothesis of shooting down the plane with a missile over Iran is not excluded, but it has not been confirmed yet.

The US Transportation Safety Agency announced that it had received a note from the Iranian civil air authorities to investigate the causes of the crash of the Ukrainian Boeing plane shortly after take-off from Tehran on Wednesday.

The agency said in a statement that it "continues to follow the situation about the plane crash and assess the level of its participation in the investigation."

She added that, "as in every investigation involving the National Transportation Safety Authority, the agency did not launch speculation about the causes" of the crash.

Under the rules of the International Civil Aviation Organization, the commission chose a representative to investigate the catastrophe, which killed 176 people, mostly Iranians and Canadians.

On Thursday, Canadian Prime Minister Justin Trudeau said that several intelligence sources, including Canadian, indicated that the Boeing 737 plane that crashed near Tehran on Wednesday "was shot down by an Iranian air-to-surface missile."

"We have information from multiple sources, including from our allies and our devices, indicating that the plane was shot down by an Iranian missile," Trudeau said. "Perhaps it was not intentional."

For his part, US President Donald Trump spoke of "doubts" about the causes of the crash of the Ukrainian passenger plane shortly after take off.

French Foreign Minister Jean-Yves Le Drian said Friday that France is ready to provide its technical expertise in the investigation of the Ukrainian plane crash if Iran makes a request.

"France is ready to contribute the necessary expertise," Lauderian told RTL radio, explaining that she had not yet received a request in this regard.
