Ukraine blames Russia after air alert app sends out false warnings

Ukraine’s Air Force said its air raid alert app sent false messages on Sunday after what it described as an alleged Russian hack. The alerts claimed there were nuclear and chemical threats near Kyiv, potential street fighting and a deployment of Russia’s hypersonic Oreshnik missile; the Air Force said there was no radiation threat. Ukraine’s strategic communications centre, SPRAVDI, also blamed Russia, while Kyiv authorities said the separate app for the capital was working normally. Hours later, Russia’s Emergencies Ministry reported a massive cyberattack on its mobile app that spread false information.
