False alerts spread
Russia’s Emergencies Ministry said its emergency warnings app came under a “massive cyberattack,” hours after Kyiv said Ukraine’s air raid alert app was hacked and sent false warnings.
“There is no radiation threat! Stay calm and follow our updates on our channel.”
The Ukrainian Air Force said on Telegram that “The air alert app appears to have been subjected to enemy influence,” and it added, “There is no radiation threat! Stay calm and follow our updates on our channel.”
The alerts included messages warning of nuclear and chemical threats around Kyiv, and an erroneous message also said Russia’s hypersonic Oreshnik missile had been deployed.
Russia said its app breach enabled attackers to spread “false information” to users, while the ministry said its broader public warning system was operating normally and had not been affected.
Ukraine’s Centre for Strategic Communications, SPRAVDI, blamed Russia for the hack in a post on X, while Kyiv authorities said a separate app for the Ukrainian capital was working normally.
Truce ends, war resumes
The announcements from Russia and Ukraine followed the end of a truce in a part of the Russian-occupied Kherson region, where the localised ceasefire began on Tuesday and ended on Sunday. Ukraine’s military announced the evacuation of 167 people from threatened areas in the Kherson region as the local ceasefire, which had lasted six days in Olenivka and surrounding areas, approached expiration at midnight local time. Ukraine’s President Volodymyr Zelenskiy said Russia targeted energy infrastructure in four Ukrainian regions overnight, causing power outages for hundreds of thousands of homes.
Zelenskiy also said Ukraine struck the Kaminsky plant in the Rostov region of Russia, and Moscow did not comment on this attack. The Russian Defense Ministry reported that its forces shot down 235 Ukrainian drones overnight, while the Ukrainian Air Force announced the downing of 371 of 433 long-range drones launched by Russia since Saturday evening.
Patriot-linked conditions
Zelenskiy told Fox News that Ukraine would stop hitting Russian oil refineries if Washington provided Kyiv with powerful Patriot interceptor missiles. Zelenskiy said, “We said that if you want us not to attack Russia’s refineries, they have not to attack our energy system,” and he added, “Another alternative, give us Patriot missiles, we will find money, not just aid.” DW reported that the United States was backing a quick resumption of Russian natural gas exports to Europe via pipelines crossing Ukraine as part of talks aimed at securing an energy ceasefire before winter.
DW also said Russia’s share in European gas supply had declined to about 11% from 45% on the eve of Moscow’s full-scale invasion of Ukraine in February 2022. The Guardian framed the immediate stakes around the hacked alert system and the renewed fighting after the Kherson ceasefire expired, while it described Ukraine’s air force warning that the app had been hacked and Russia’s claim of a “massive cyber-attack” on its emergency app.
