During the evening address on Aug. 18, Volodymyr Zelenskyy said that he had called on Guterres to use all UN powers to ensure that the aggressor country fulfills all norms of international law regarding Ukrainian prisoners.

The General Staff of the Ukrainian Armed Forces said on July 29 that the Russian Federation had struck the prison colony in Olenivka in order to accuse Ukraine of committing war crimes, as well as to cover up the torture of prisoners and executions, which it said were carried out on the orders of the occupation administration and commanders in Russian-occupied Donetsk Oblast.
