Russia kept up its aerial attacks on Ukraine Tuesday, part of a strategy that is now clear after eight days—Moscow is trying to cripple Ukraine's power and water plants. President Volodymyr Zelensky said on Twitter that "30% of Ukraine's power stations have been destroyed, causing massive blackouts across the country," per the BBC. There is now "no space left for negotiations with Putin's regime," he added, per the AP. The missile and drone strikes have struck not just the capital of Kyiv but cities elsewhere, too. Related:
