‘Invasion’

Two days after talks took place in Minsk between the Ukrainian president Petro Poroshenko and his Russian counterpart Vladimir Putin, Kiev accused Russia on 28 August of having "deployed army units on the Ukrainian territory", reports Den.
According to the Kiev daily,

Previously Russia has supplied heavy weapons and mercenaries to the self-proclaimed Donetsk People’s Republic. Now we are already talking about a direct invasion of Russian troops on the Ukrainian territory. The day before yesterday, the Russian military took over the town of Novoazovsk as well as a number of neighboring villages.
As for the Western reactions, columnist Mikola Siruk believes that —
recent talks in Minsk showed that the West does not have a unified position. And I think the most destructive position comes from Berlin and Paris — they are flirting with Putin and his fears, and they reject his political isolation. Putin actually taught the West that he will act as he wishes. And now he wants to dictate terms to Europe and change the world order, using Ukraine as a place for self-affirmation. His tactical goals are to force Ukraine to abandon the Association agreement with the EU in the current form, and to force the West to recognize Russian Crimea. Unfortunately, the western world has already lost to Putin and NATO and showed its weakness and inability to respond to the new global challenges.
