The NSDC secretary noted that Ukraine was finding out who might be interested in the plane crash.
"We have three closed versions that we are working on. Including who was interested in this and who was involved in it," Danilov said.
He also added that he had been able to reach "certain agreements" during his visit to Iran.
It should be noted that Oleksii Danilov paid a working visit to Iran on February 15-17 in order to discuss the problematic issues of investigation of the PS752 plane crash.
As we reported earlier, according to Iranian Defense Minister Amir Hatami, the black box of the Ukrainian plane PS752, downed on January 8, 2020, in Iran is heavily damaged and it is impossible to get the information from it.
“It was decided to finish the repair of the black box first and then to try to decrypt it. Currently, they are behind on the repairs,” the minister said.
