On the 9th, the ukrainian government's latest statement on whether it was involved in a mechanical failure was not ruled out as the main cause of the crash. Ukraine's top security chief, citing an unconfirmed photo on social media, claimed the airliner could have been shot down by a Russian-made missile.
Reuters, analyzing photos of the scene of the crash released by Iranian media, found a suspected bullet hole in some of the wing and other wreckage. But some western intelligence sources believe the crash was more likely due to a mechanical failure,\" there is evidence that an aircraft engine overheats.\"
9, Iran's civil aviation organization said in its initial report that two black boxes have been found damaged, part of the memory storage lost. The crew did not release any emergency radio messages. Witnesses said the plane caught fire before it went down.
Russian satellite news agency reported on Sunday that Ukraine's National Security Council secretary, Oleksiy Danylov, said on social media that the government was investigating possible causes of the crash, including the impact of missiles, drones and other flying objects, terrorist attacks and engine failures.
Denisov added that there was a claim on the network that \"Russian missile remains were found at the scene of the crash.\" \"A mainstream theory is that the airliner could be shot down by a'Doyle' anti-aircraft missile system. But he didn't start, saying only that Ukrainian investigators wanted to investigate.
The survey's news site, Bellingcat, responded that it had indeed seen photographs of the so-called \"Russian-style missile wreckage,\" but only based on its shooting angle could not determine whether it was at the scene of the crash in Tehran.
At 5 a.m. local time on 8 a.m., a Ukrainian International Air Boeing 737 exploded shortly after taking off from Iran's capital, Tehran's Khomeini International Airport. All 176 people were killed on board.

Shortly after the incident, the ukrainian embassy in iran issued a statement that ruled out a possible terrorist attack and believed it was a mechanical failure that caused the crash. However, the embassy withdrew the statement that night, emphasizing that it would be announced by the commission of inquiry, any previous statement is not valid.
A Canadian security official said the initial assessment by Western intelligence agencies suggested that, although there was no evidence, the chances of the plane being hit by a missile were slim.
The iranian civil aviation organization said it had found the black box at the scene of the crash and invited ukraine, canada and sweden to participate in the investigation. Mr Abezad, the head, said the black box would not be handed over to Boeing or any U.S. manufacturer.
9, the group issued a preliminary report confirming that two \"black boxes\" containing flight data and cockpit communications records have been damaged and that some memory storage has been lost.
The report said the crew members did not release any radio messages with unusual conditions and ruled out the possibility of a laser or electromagnetic interference causing the crash. Witnesses said the plane had turned to fly back to the airport shortly after take-off and had caught fire before the crash.
