In the February 1 article of the Ukrainska Pravda, Yusov said: Ukraine has made and will continue to make demands on the remains. However, until now, Russia has not done so. That is why we call on the international community to conduct a fair investigation into the Il-76 crash, as well as to determine what was on board, including personnel, ammunition, pilots and other personnel. So far, the Russian side has not confirmed that this is already underway.
Earlier, an Il-76 military transport plane crashed at eleven o'clock in the morning of January 24 in the Belgorod region of Russia. The Russian Ministry of Defense announced that there were 65 Ukrainian prisoners of war on board, 6 crew members, 3 escorts, none of whom survived.
In a statement released on the same day, Russia said that Ukraine was fully aware of the process of exchanging prisoners, and also knew the ways and methods of transportation, and that the attack on the plane was a deliberate act, showing that Ukraine did not comply with the agreement. Ukraine said at the UN General Assembly meeting the next day that Russia had not informed Ukraine in advance of the details of the plane, and that all responsibility should be borne by Russia.
The crash site. 
After the incident, the Russian investigation team determined that the case was a "terrorist attack" and investigated it. Russia's "Kommersant" newspaper said on February 1 that Russian investigators found some wreckage at the scene under two attacks by the US Patriot air defense missile system, and these wreckage "belong to the US Patriot composite anti-aircraft missile MIM-104A from its design features, geometry and existing traces." The fragments of the missile hit the engine and hit the ground in a matter of seconds and occurred**. Researchers collected the remains of more than 670 victims and identified them through genetic analysis.
The Russian investigation team said that the remains of 116 bodies and the wreckage of two rockets marked in English were located in the northeast of the crash site18 km and 4 to the southeast8 km away. After testing for chemical composition, the Russians detected trace amounts of hexene and up to 10% impurities in their cleaning fluids, which are typical of foreign-made explosives.
In the case of Dmytro Lubinez, a member of the Human Rights Committee of the Ukrainian Parliament, Russia has no reason to believe that Ukrainian prisoners were being held on the plane and has refused to allow international experts to investigate it, and if there is no evidence, they are likely to blame Ukraine for the deaths of these prisoners.
