"Iran considers the US fighter jets' threats as blatant instance of the violation of international law, regulations and aviation standards," the CAOI wrote in a communique on Friday.
After the threats by the US fighter jets on Mahan Airline's Flight 1152 over the Syrian skies on Thursday (July 23) and in international air corridors which was flying from Tehran's Imam Khomeini Airport to Beirut some passengers were injured as a result of reaction by Mahan Airline pilot in order to avoid collision with hostile fighter jets, parts of the communique said.
It added that after the Mahan passenger plane landed at Beirut International Airport and after ensuring that the threatened plane was in good shape and condition, the decision for return of the plane was taken.
"The Civil Aviation Organization of Iran on the basis of the contents of the appendix 13 of Chicago Treaty while contacting the Syrian side has called for swift and precise investigation into the incident and the technical team of Iran has started technical investigation after the plane landed at Imam Khomeini International Airport. The details of this incident will be released after studying all technical data and information in accordance with investigating the incident and also some documented and compelling information given by the Syrian aviation offiial," it added.
The Civil Aviation Organization of Iran considers the US fighter jets attempt to threaten the Iranian passenger plane as an instance of the blatant violation of international law, as well as aviation regulations and standards and it officially presents its serious protest to ICAO and calls for immediate probe into the matter.
Two US fighter jets approached a Mahan Air Tehran-Beirut flight over the Syrian sky in a highly risky move and the captain of the Iranian passenger plane was forced to make a sudden change of direction and altitude, causing several injuries.
The captain of Mahan Air Flight No. 1152 later said the pilots of the two hostile planes have identified themselves as US army pilots during a radio contact.
A video posted by a reporter of Iran's state-run TV who was aboard the plane showed an F-15 fighter jet from the window of the plane and comments from a passenger who had blood on his face.
In a later interview from Beirut, the reporter said three passengers have been wounded during "the US planes' intentional move".
Iranian Foreign Ministry Spokesman Seyed Abbas Mousavi said Iran's Ambassador to the UN Majid Takht-Ravanchi has informed the UN Secretary-General Antonio Guterres of the incident, and warned that "in case of any incident for this plane on the way back home, the Islamic Republic of Iran will take the United States reponsible".
"A similar message has been sent to the Swiss ambassador to Tehran," the spokesman added. The Swiss embassy hosts the US interests section in Iran in absence of formal diplomatic ties between the two countries.
Mahan Air told FNA later that several passengers have been wounded during the incident and have been taken to a hospital in Beirut and others have evacuated the plane sound and safe.
It said the passenger jetliner refueled to fly back to Iran.
The jetliner flew back home early Friday morning.
