Ukraine launched drone strikes against Yandex data centres in the Kaluga, Sasovo, and Ryazan regions. These attacks targeted facilities including those housing supercomputers for AI development, resulting in service disruptions.
President Volodymyr Zelensky described the operations as a mirror and symmetrical response to Russian missile strikes on Ukrainian server facilities in Kyiv. Ukraine's defence ministry stated the goal is to disrupt the revenue of Moscow's war machine.
