U.S. and Russian diplomats clash over Ukraine at U.N.

The United States and Russia engaged in a bitter diplomatic brawl Monday at the U.N. Security Council over the Ukraine crisis, as the Americans accused the Russians of endangering peace by massing troops on Ukraine’s borders while Kremlin diplomats dismissed what they called hysterical U.S. fearmongering.

“The situation we are facing in Europe is urgent and dangerous,” the United States ambassador, Linda Thomas-Greenfield said in her opening remarks. “Russia’s actions strike at the very heart of the U.N. charter.”
