It also said that the plane took off from Tehran at 6:12 a.m. local time and lost all contact with air traffic control at 8,100 feet.

The aircraft disappeared from secondary surveillance radar screens at 6:15 a.m. and from primary surveillance radars at 6:18 a.m.

The aircraft moved past a residential area and its first physical contact with the ground was at a public park. The plane was torn apart as it moved through a football pitch, nearby farmland and gardens.

The retrieved flight data recorder and the cockpit voice recorder are "some of the most advanced equipment of their kind in the world" and Iran lacks the facilities to decode them.

French and U.S. accident investigation agencies have refused to send necessary equipment to Iran for decoding the black boxes.

As UNIAN reported earlier, Kyiv-bound UIA flight PS752 crashed shortly after takeoff from Tehran's Imam Khomeini International Airport in the early hours of January 8. It was carrying 167 passengers and nine crew members on board.

Two passengers, Olena Malakhova and Olha Kobyuk, and the crew were Ukrainians: Volodymyr Haponenko, Oleksiy Naumkin, Serniy Khomenko, Kateryna Statnik, Ihor Matkov, Maria Mykytyuk, Denys Lykhno, Valeria Ovcharuk, Yulia Solohub. There were also citizens of Iran, Canada, Sweden, Afghanistan, Germany and the United Kingdom. There were no survivors.

On January 11, Iranian President Hassan Rouhani officially admitted that the Ukrainian airliner had been shot down by accident as a result of a "human error."

An Il-76 plane with the Ukrainian victims' bodies arrived in Kyiv on January 19.
