MOSCOW (Reuters) - Russia warned the United States on Saturday that any armed action by Ukrainian authorities in the east of Ukraine would undermine efforts at a diplomatic solution to the conflict and put planned peace talks at risk.
Russian Foreign Minister Sergei Lavrov made the warning during a call from U.S. Secretary of State John Kerry, who expressed concern about Russia's role in "inciting" trouble in eastern Ukraine, the Russian Foreign Ministry said in a statement. Separatists have seized state premises in eastern Ukrainian towns in recent days.
