Volodymyr Zelenskyy stated this in his evening address.
"Every occupier who mocks Ukrainians, who tortures and kills, should know that there will be retribution for this. Even if some of the Russian killers hope that they will not be brought to justice, that they will hide somewhere, let them know: they will be responsible for what they have done anyway. Geography, time, borders and walls will not stop a retribution. There should be a clear legal recognition of Russia as a terrorist state. Russia has proven with numerous terrorist attacks that it is the biggest source of terrorism in today's world. This is a fact", the President of Ukraine emphasized.
