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 requesting a meeting within the next 48 hours for “transparency” about Russia’s plans.
Russia has denied any plans to invade Ukraine despite the build-up of some 100,000 soldiers on Ukraine’s borders.
Mr Kuleba said Ukraine had, on Friday, demanded answers from Russia under the rules of the Vienna Document, an agreement about security issues adopted by the members of the Organisation for Security and Cooperation in Europe (OSCE), which includes Russia.
“If Russia is serious when it talks about the indivisibility of security in the OSCE space, it must fulfil its commitment to military transparency in order to de-escalate tensions and enhance security for all,” he said.
