WASHINGTON — The United States has warned Russia against stirring separatist sentiment in eastern Ukraine, following unrest in several cities in recent days. U.S. officials said there are clear signs that pro-Russian demonstrations were orchestrated from outside. Meanwhile, recent events in Ukraine have emboldened Russian-speaking separatists in Moldova to renew their calls for independence, with a view of joining the Russian Federation.
Pro-Russian demonstrators in eastern Ukraine and in Moldova are calling for a referendum similar to the one that led to Russia's annexation of Crimea last month.
