Russia is waging a war against Ukraine, although it would not admit it officially, Ukrainian President Petro Poroshenko has said.

"Despite the fact that Russia has so far refused to formally admit its direct military intervention, today there is no doubt that this is an aggressive war aimed against my country, against Ukraine," Poroshenko told the UN General Assembly in New York on Tuesday.

The UN GA passed a resolution supporting Ukraine's territorial integrity and sovereignty and condemning the annexation of Crimea, the president. "It is regretful that after this clear verdict by international community Russia failed to return into the civilized international legal field. Moreover, Moscow started a new military, reckless game in Donbas," Poroshenko said.

He also said that Russia is misleading international community by asked its military servicemen to remove insignia from military vehicles and "rejecting its soldiers who were captured on the battlefield.' "I want to stress that this is neither a civil war, nor a domestic conflict," Poroshenko said, saying that Ukraine "had to fight Russia's regular troops armed with heavy weapons."

He claimed that Russia occupied about 44,000 square kilometers of Ukrainian territory in Crimea and Donbas. "The Ukrainian territories occupied by Russia in Crimea and Donbas amount to approximately 44,000 square kilometers," said the president, adding that what is happening in Ukraine is neither a civil war nor a domestic conflict.

In his speech to the UN General Assembly Poroshenko also accused Russia of surrounding itself with a belt of frozen conflicts. "In the more than 23 years since the dubious procedure of the permanent Security Council membership handover from the former Soviet Union to the Russian Federation, Russia has not just started hybrid wars. In reality, to retain clout in neighboring countries, for decades Russia has deliberately been creating a belt of instability around itself. One can talk of Nagorno-Karabakh, Transdniestria, Abkhazia, South Ossetia, Crimea, Donbas," Poroshenko said.

These conflicts are supported by or directly linked to Russia, he said. "Now Russia's little green men ended up in Syria. What and who will be next?" the Ukrainian leader said.

He also questioned the sincerity of Russia's proposal to set up a broad anti-terrorist coalition. "Over the past few days we have heard Russia's reconciliatory statements in which it called, in particular, for the creation of an anti-terrorist coalition and pointed to the high-fire risk of flirting with terrorists. Beautifully said, but it is very hard to believe," Poroshenko said.

It is odd that while calling for an anti-terrorist coalition Russia is inciting terrorism at its door, he said. He accused Moscow of "starting the war at the expense of puppet governments."

He also denied Russia the right to speak about peoples' freedom while "punishing its neighbor for its choice" and "respecting no one."
