Ukraine’s Air Force has said its air raid alert app sent erroneous messages after allegedly being hacked by Russia.

Fake alerts warning of nuclear and chemical threats to areas in and around Kyiv were sent on Sunday, along with warnings of potential street combat. An erroneous message also said Russia’s hypersonic Oreshnik missile had been deployed.

“The air alert app appears to have been subjected to enemy influence,” the Ukrainian Air Force said on Telegram on Sunday. “There is no radiation threat! Stay calm and follow our updates on our channel.”

SPRAVDI, Ukraine’s Centre for Strategic Communications, blamed Russia for the hack in a post on X.

The raid alert app is used across Ukraine to warn people in real time of incoming Russian air attacks. A separate app, specifically for the Ukrainian capital, was working normally, according to Kyiv authorities.

Hours later, early on Monday morning, Russia’s Emergencies Ministry said its mobile app had been hit by a “massive cyberattack”.

The ministry said on Telegram that the attack led to the spread of “false information”.

Russia’s and Ukraine’s announcements follow the end of a truce between the two countries in Kherson .

The localised ceasefire , which began on Tuesday and ended on Sunday, was the longest of the war so far.

俄罗斯紧急情况部还表示，其移动应用程序遭受了“大规模网络攻击”，导致出现“虚假信息”。

乌克兰空军表示，其空袭警报应用程序在疑似遭到俄罗斯黑客攻击后发出了错误信息。

周日，基辅及其周边地区收到虚假警报，声称面临核生化威胁，并可能爆发巷战。一条错误信息还称，俄罗斯已部署了高超音速“奥列什尼克”导弹。

几个小时后，周一清晨，俄罗斯紧急情况部表示，其移动应用程序遭到了“大规模网络攻击”。

该部在 Telegram 上表示，此次袭击导致了“虚假信息”的传播。

俄罗斯和乌克兰的声明是在两国在赫尔松的停火协议结束后发布的。
