The U.N. Security Council met for the 26th time in emergency session on Ukraine as the U.N. warned of a possible return to “full-scale fighting” in the rebel-held east. U.S. Ambassador Samantha Power mentioned that Russia tries to escalate situation in Ukraine. She mentioned occupied regions of Georgia .  "The problem is and as it has long been throughout this crisis is you can not reach a political solution if only one side is committed to forging it. And you can not effectively implement a roadmap with parties who like the Russians and the separatists they back so consistently fail to keep their word. We have seen Russia"s playbook in Transnistria, South Ossetia, Abkhazia and Crimea. So the question is not what Russia will try to do in eastern Ukraine. The question is what we the international community will seek to do to prevent yet another frozen conflict in Europe manufactured by Russia. "- Samanta Power stated.

The  meeting  at UN came hours after NATO’s top commander said new columns of Russian troops and tanks have rolled into eastern Ukraine, which Moscow promptly denied.
