An air alert app in Ukraine sent out false warnings, Al Jazeera English reported. Ukraine blames Russia for the warnings, according to the outlet. Separately, Russia's Emergencies Ministry says its mobile app suffered a "massive cyberattack" that led to "false information", Al Jazeera English reported. Ukraine's attribution and the ministry's statement are claims. The account comes from one outlet and has not been independently verified.
Details such as which app was affected, how many users received the warnings, when the incidents happened and what evidence Ukraine has were not provided. It is unclear whether the two incidents are connected.
