Ukrainian drones struck a Siberian oil refinery Saturday and disrupted an Urals athletics competition, as Kazakhstan’s president told Russia’s Vladimir Putin the Ukraine war should end during a forum in Siberia’s Omsk. In occupied Ukraine, Russian-installed authorities said a Ukrainian strike had killed 12 people at a seaside “tourist camp”, as well as one more in a Moscow-held town and two in Russian border villages.JOIN US ON TELEGRAMFollow our coverage of the war on the @Kyivpost_official. Kyiv said Russian attacks killed five people in eastern and southern Ukraine. The deaths come as the UN has warned of civilians dying in larger numbers recently in the almost 4.5-year war. US-led talks on ending fighting have stalled, and the Kremlin said it intends to seize the rest of east Ukraine. Moscow said Ukraine -- which has intensified its retaliatory strikes -- launched more than 300 drones into Russia, including on far-flung regions, Saturday. The governor of Siberia’s Tyumen region said a local oil refinery was set ablaze, while Russia’s athletics federation said an all-Russian competition in the Urals city of Yekaterinburg was halted over drone threats. Ukraine’s Volodymyr Zelensky claimed the Siberia strike and said Kyiv had hit a military factory in the Kirov region for a second day in a row, a day after an attack there killed five people, according to local authorities. Kyiv has said its retaliatory strikes are aimed at damaging Moscow’s war effort and forcing the Kremlin to negotiate.
