Hacked Russian TV and radio stations broadcast startling messages of a nuclear attack and urged residents to put on gas masks and run for cover. On Thursday, reisdents in eastern Russia were told to "take potassium iodide pills" and take shelter immediately in the hacked broadcast, according to a report from Metro. "There was a strike. Urgently go to a shelter," viewers of TV were told as a map of Russia displayed the country turning red from west to east. "Seal the premises. Use gas masks of all types. In the absence of gas masks, use cotton-gauze bandages." Screens also displayed a black and yellow radiation warning with a message urging people "immediately to shelter." The messages were seen on TV and heard on radio stations in the Moscow and Sverdlovsk regions. The messages also interrupted programming in Yekaterinburg, Russia's fourth-largest city.
