Drawing of a significant amount of heavy military equipment of Russia’s Armed Forces to the annexed Crimea and temporarily occupied territories of Donbas could mean Moscow’s preparing for offensive operations against the Armed Forces of Ukraine dedicated to the independence anniversary of Ukraine, Ukraine's representative in the security subgroup of the Trilateral Contact Group for a peaceful settlement of the situation in Donbas Yevhen Marchuk has said.

"Russia publicly supplies a large number of heavy military equipment, mainly of offensive character, to Crimea and the occupied territories of Donbas ... In my opinion, Russia is simply preparing to celebrate the 25th anniversary of Ukraine's independence. Perhaps, in the way she did it in 2014, but only with some amendments to the current realities," Marchuk wrote on his Facebook page on Tuesday.

According to Yevhen Marchuk, Russia can not put up with the 25th anniversary of Ukrainian independence happening smoothly. The fact that "Kyiv will host the leaders of the leading world countries" frustrates them [Russian Federation].

"Even if Russia does not dare to repeat the events of August 2014, the situation - created by them - of a high probability of serious escalation will inevitably produce highly hypothetical threats to the personal safety of distinguished guests and refusal to travel to Kyiv. I think that Russia has already developed and activated its plan, which is designed to ruin and disrupt the celebration of the 25th anniversary of independence of Ukraine," Marchuk said.

Marchuk noted that the Ukrainian security and defense system "has already gained decent experience in countering the aggressor’s actions and actively working to ensure the safety of the 25th anniversary of independence throughout Ukraine, not only in Kyiv."
