According to the regional governor, two residential buildings and an industrial facility were impacted, with the Ukrainian military reportedly targeting the Ryazan oil refinery, Russia’s third-largest. The Ukrainian General Staff noted a substantial fire in the area, coinciding with one of the most extensive Russian aerial assaults on Ukraine to date, which has resulted in at least 24 deaths in Kyiv from a destroyed residential block. Additionally, Russia and Ukraine conducted a prisoner exchange of 205 individuals as part of a temporary ceasefire agreement during the Russian Victory Day celebrations on May 9.
