UNITED NATIONS (Reuters) - Western nations and Russia traded accusations at the United Nations on Friday over the recent upsurge in violence in eastern Ukraine, while a senior member of an international monitoring team blamed both sides in the conflict for breaking a ceasefire.

The diplomatic clash between European, U.S. and Russian envoys came a day after Ukraine warned of a possible "full-scale invasion" by Russia, following the worst fighting with Russian-backed separatists in months.
