EU, U.S. present Russia with united sanctions, energy front - draft

Gas pipelines are seen in the Gazprom gas pumping station near the village of Pisarevskaya, some 280 km (173.9 miles) from the central Russian city of Voronezh December 16, 2005.

BRUSSELS (Reuters) - U.S. and EU leaders will on Wednesday pledge to work together on sanctions and on strengthening the energy security of Europe and Ukraine, as they seek to present a united front to Russia, a draft document said.

U.S. Secretary of State John Kerry and Energy Secretary Ernest Moniz are in Brussels for talks after a year in which the United States has led the push for tougher sanctions, while some governments in Europe, afraid economic measures against Russia will hurt them as much as they hurt Moscow, have been more cautious.
