Nuclear radiation in Russia and Ukraine? No, just hacked warning alerts

Ukraine and Russia accused each other of hacking emergency alert systems after fake notifications about nuclear and chemical threats were sent on Sunday and Monday. Ukraine’s Air Force said its Air Alert app issued warnings for Kyiv and nearby areas, along with alerts about possible street fighting and the deployment of Russia’s hypersonic Oreshnik missile. The false warnings came as a six-day localised ceasefire in Russian-occupied Kherson ended, with residents expecting fighting along the front lines to resume.
