Did Ukraine destroyed Russian military escort?

This morning correspondents Sean Walker from "The Guardian" and Roland Olifent from "The Telegraph" reported on Twitter that the Russian military equipment crossed the Ukrainian border. And the president of Ukraine Petro Poroshenko, in turn, declared that the Russian escort was destroyed by the Ukrainian military. But for real, think, how it can be possible when Ukraine's government's army can't even beat pro-Russian separatists.

So, answer of the Russian side was next: messages on crossing border of Ukraine by Russian military aren't true. For sure, it is another lie from the Ukrainian government.

"No Russian military column crossed the Russian-Ukrainian border at night, in the afternoon or at any other time. It will be the best of all if the Ukrainian artillery destroyed the phantom, instead of refugees or own military personnel. It is sad that journalistic gossips on social networks like Twitter become a reason for top-level loud statements in the modern world" — the official representative of the Russian military department major general Igor Konashenkov said.
