0:20Screenshots show false Ukrainian warnings about radiation, chemical threats and street fighting.
0:38Russia's emergency ministry reports that its mobile app also sent fake notifications after a cyberattack.
0:53Dan Johnson explains the confusion in Kyiv and officials' reassurance that air defence itself was not compromised.
3:13Vitaly Shevchenko places the reported Russian app attack within hours of the Ukrainian breach.
4:49Shevchenko says both countries have advanced cyber capabilities, but state responsibility for either attack remains unproven.

The attacks came within hours of each other: first false emergency warnings in Ukraine, then a reported breach of Russia's emergency app. The sequence is central to a report from BBC News, the British Broadcasting Corporation's news service in the United Kingdom, but its analyst cautions against treating it as proof of responsibility.

Screenshots show Ukrainian notifications warning of radiation hazards, chemical threats and street fighting, telling recipients not to go outside. Another message invoked a nuclear alert. Reporting from Kyiv, correspondent Dan Johnson explains that many residents use the app as a backup to air-raid sirens in the streets, making the false messages a source of confusion over whether to seek safety.

Ukraine's Air Force used separate communication channels to say there was no such threat. Johnson reports that officials also sought to reassure residents that the actual air defence system had not been compromised. Ukrainian authorities blamed Russian interference.

Russia's Ministry of Emergency Situations subsequently reported what it called a "massive cyber-attack" on its own app, with specialists working to restore service. Moscow did not immediately identify a suspected perpetrator.

Vitaly Shevchenko, chief analyst at BBC Monitoring, says the Russian incident followed the Ukrainian breach within hours. Both countries have the capability to mount such attacks, he explains, but capability and timing are not evidence that either government was responsible. "At the moment of speaking, I've seen no credible evidence that it's the Russians that did it," he says of the Ukrainian app attack.
