Ukrainian authorities say Russia’s biggest cities are bound to suffer attacks as a result of the Kremlin’s war against Ukraine. “Internal escalation of the war in Russia is inevitable,” said Mykhailo Podolyak, an adviser to the Ukrainian president. “Cities that are pampered, lazy, that thought they lived in a different reality, such as Moscow, St. Petersburg, and Yekaterinburg, will be subject to strikes,” he said, stressing that Ukraine itself has no plans to carry out such attacks. But the “logic of war” means that all of Russia will be dragged into what the Kremlin started, he said. “Various blows will be dealt to various targets. Why, by whom, and what for? That’s another question,” he said. His comments came as authorities in Moscow were spotted installing air defense systems on the rooftops of some buildings, a move interpreted by some as paranoia over possible drone strikes, and by others as nothing more than a domestic propaganda ploy.
