Russia and Ukraine have reported cyberattacks on emergency alert apps after a localised ceasefire ended, spreading false warnings on both sides.
Ukraine reported false radiation warnings in Kyiv, while Russia said false alerts spread across 33 regions. No group has claimed responsibility.
Alert apps are now part of the war's infrastructure, and faking them is a cheap way to sow panic. Both sides are investigating.
