During the Tuesday session, Verkhovna Rada (the Ukaranian Parliament) agreed to recognize Russia as an aggressor state, and self-proclaimed Donetsk and Luhansk people's republics as terrorist organizations. The initiative was supported by 271 out of 289 deputies present at the vote.

The deputies issued a statement, addressed to the United Nations, the European Parliament, the Parliamentary Assembly of the Council of Europe (PACE), the NATO Parliamentary Assembly, the GUAM Parliamentary Assembly calling on them to recognize Russia as an aggressor state in the Ukrainian conflict.

That move, if supported by the international community, defines the situation more clearly and shows one major enemy. Still, the science director of the Institute for Euro-Atlantic Cooperation told Deutsche Welle, recognition of Russia as an aggressor state does not mean breaking diplomatic or trade contacts with it.

Moreover, the MPs address the international community to provide military-political support for Ukraine and exclude Russia from the UN Security Council.  Russia has a right to block UN decisions and actively implements this when it comes to decisions concerning the situation in Donbass region.

"Ukraine remains an object of aggression on behalf of Russia, which it conducts through support and supply of major terrorist attacks,” the statement reads. “In less than two weeks, over 50 peaceful citizens of Ukraine were killed in Volnovakha, Donetsk and Mariupol over the shelling and actions by terrorists supported by Russia.”

Russian MPs say that this move will not remain unanswered. “Obviously, this event requires consideration of the plenary meeting and adoption of a relevant document," said Vasily Likhachev, member of Duma’s Committee on CIS Affairs, RBC reports.

The UN resolution adopted on 14 December 1974 states that a war of aggression is a crime against international peace, but not every act of aggression is. Though states would nevertheless hold responsibility for acts of aggression.

According to the United Nations definition, aggression is “the use of armed force by a State against the sovereignty, territorial integrity or political independence of another State, or in any other manner inconsistent with the Charter of the United Nations, as set out in this Definition. Article two of the resolution says: “The First use of armed force by a State in contravention of the Charter shall constitute prima facie evidence of an act of aggression.”

According to the UN report on the situation in Ukraine from 23 January 2015, there are over 920 000 internally displaced people. 600,000 fled to other countries. More than 5,000 were killed and at least 10,000 wounded.
