False Nuclear Alerts Hit Ukraine App

For a brief period on Sunday, the digital alert system used across Ukraine displayed false warnings of nuclear and chemical threats. The error appeared in the air raid application that citizens use to track incoming airstrikes. The air force later confirmed the app was likely the target of a cyber intrusion.

The malfunction showed specific regions, including Kyiv, as subject to high-level alerts. It also generated an erroneous notification stating that Russia had deployed its Oreshnik hypersonic missile. The air force posted on Telegram that the system appeared to have been subjected to enemy influence. Officials instructed the public to remain calm and noted there was no radiation threat.

Hours after the Ukrainian incident, Russian authorities reported a similar disruption. The Ministry of Emergencies stated that its mobile application for warning citizens of drone attacks had suffered a massive cyberattack. The ministry explained that the breach allowed attackers to broadcast false information to the public.

On the ground, military operations continued in southern Kherson region. Ukrainian forces evacuated 167 residents on Sunday as a temporary local ceasefire expired. This truce, which lasted six days, was mediated by US First Lady Melania Trump and Pope Leo. It followed the evacuation of residents from the Russian-held town of Oleshky by bus two days prior.

No violations were reported by either side during the truce. One Ukrainian lawmaker described the period as the biggest de-escalation since 2022. However, Kherson regional governor Oleksandr Prokudin urged locals to stay vigilant as the calm ended. He advised residents to respond immediately to warnings about Russian attacks.

A Ukrainian military officer speaking to AFP expressed concern that fighting would intensify once resumed. The officer noted that Russian forces used the quiet period to amass troops, transport ammunition, and gather intelligence via surveillance drones. US-mediated talks between Russia and Ukraine are scheduled to resume this month after a freeze that began in February.

Separate from the cyber incidents, Ukraine resumed strikes on Russian oil refineries. Long-range drones targeted the Kstovo refinery in Nizhny Novgorod oblast and a major facility in Samara oblast owned by Rosneft. President Volodymyr Zelenskyy told Fox News on Sunday that Ukraine would pause these attacks if Washington provided Patriot interceptor missiles. The US State Department approved the sale of 500 Patriots on Friday, but Zelenskyy warned deliveries could take years.
