Asked by an UNIAN reporter, why the Russian generals said two years ago that they had seen a Ukrainian Su-25 on their radar screens close to MH17, and now, referring to the same radar data, they say that any airborne side objects that could cause the destruction of the aircraft were not observed in the area of a disaster, Peskov said that he could not answer this question.

"The professionals who understand the radar readings should be the ones to answer this question. I recommend addressing this issue to the Ministry of Defense. If yesterday's briefing did not include questions, it does not mean that you cannot ask your question today," he said.

As UNIAN reported earlier, on July 21, 2014, the Russian Defense Ministry claimed that a Ukrainian warplane flew close to MH17 on the day of the disaster.

Dutch Safety Board, which has been probing into the circumstances of the MH17 crash, concluded last year that a Buk missile had shot down the Malaysian airline and that it had been fired from a militant-controlled territory in Donbas. However, the investigation did not specify who had fired the missile.
