Following the mutiny of Wagner PMC leader Yevgeny Prigozhin in late June, the Kremlin reported that mercenaries were relocating to Belarus.
On June 27, self-proclaimed President of Belarus Alexander Lukashenko confirmed the arrival of Yevgeny Prigozhin in the country. According to him, Wagner mercenaries who arrived with him will not guard the Russian tactical nuclear weapons deployed there. However, Lukashenko emphasized that he expects the mercenaries to help in the defense of Belarus. He refrained from specifying the source of potential threats that Belarus aims to defend against.
Later, on July 23, self-proclaimed President of Belarus Alexander Lukashenko announced the desire of mercenaries from the Russian Wagner PMC stationed in his country to "go on an excursion" to Poland.
