Ukraine has called for a meeting with Russia and other members of a key European security group over the escalating tensions on its border. Foreign Minister Dmytro Kuleba said Russia had ignored formal requests to explain the build-up of troops. He said the next step was to request a meeting within the next 48 hours for transparency about Russia's plans.
Russia has denied any plans to invade Ukraine.
Meanwhile, More than a dozen nations have urged their citizens to leave Ukraine, and some have pulled embassy
staff from the capital.
