Choose the next sentence.A new buildup of Russian troops along the Ukraine border raised concerns Tuesday that Moscow might be contemplating another intervention like the one that annexed Crimea earlier this year. According to a NATO official, Russia now has about 20,000 troops stationed "in an area along the entire border with eastern Ukraine." The buildup nearly doubled the troop deployment in the last week by adding 8,000 more forces to 12,000 already there, the official said. It comes a week after the United States and the European Union increased economic sanctions on Russia for supporting pro-Russian separatists fighting Ukraine government forces in the eastern regions of Donetsk and Luhansk, along the border with Russia.
