BRUSSELS, March 2 (Xinhua) -- The NATO on Sunday condemned Russia's "military escalation" in Crimea of southern Ukraine and expressed "grave concern" regarding the authorization by the Russian Parliament to use armed forces on the territory of Ukraine.
"Military action against Ukraine by forces of the Russian Federation is a breach of international law and contravenes the principles of the NATO-Russia Council and the Partnership for Peace," the NATO said in a statement.
The bloc said Russia must respect its obligations under the United Nations Charter and the spirit and principles of the OSCE (the Organization for Security and Cooperation in Europe), urging Russia to "de-escalate tensions."
The NATO called on Russia to withdraw its forces to its bases and to "refrain from any interference elsewhere in Ukraine."
Furthermore, the bloc urged "both parties to immediately seek a peaceful resolution through bilateral dialogue, with international facilitation, as appropriate," and through dispatch of international observers under the auspices of the United Nations Security Council or the OSCE.
The NATO said it will continue to support Ukrainian sovereignty and territorial integrity, and "the right of the Ukrainian people to determine their own future, without outside interference."
