Ukraine received a new Iris-T air defense launcher from Germany on Saturday, President Volodymyr Zelenskiy said on Sunday, asking for more provision of air defense ammunition. "We also need missiles for air defense systems to have sufficient capabilities to repel Russian attacks," Zelenskiy said on Telegram. On Sunday, Ukraine's military said it had struck Russia's Saratov oil refinery overnight, causing a large fire to break out at the facility. The military said in a post on Telegram that it had also hit the Lazarevo oil pumping station in Russia's Kirov region.
