“The Ministry of Foreign Affairs recommends that citizens of Ukraine refrain from any trips to the Russian Federation, and those who are in this country should immediately leave its territory,” the Ukrainian Foreign Ministry said in a statement.
Failure to follow these recommendations "would make it much more difficult to provide adequate protection to Ukrainian citizens," Kiev added.
Earlier, Ukrainian Foreign Minister Dmitry Kuleba announced his support for the idea of breaking off diplomatic relations with Russia.
Deputy head of the Russian Foreign Ministry Andrei Rudenko said that Russia does not want to break off diplomatic relations with Ukraine.
