Ukraine and Russia say emergency air-raid warning systems hit by cyber-hacks – Europe live | World news

Timeline of Alarming Alerts

In Kyiv, residents received a succession of unusual alerts late on Sunday night over the period of roughly an hour.

Typically, people can receive several alerts a day warning of incoming Russian drones or missiles; locals after four years of living in a warzone are used to their phones going off, often followed by sirens in the street.

But these messages warned of radically different threats- a nuclear radiation warning, a chemical attack and even an incident of street fighting in Kyiv.

One of the messages was also transmitted in Russian, a clear tell that something was potentially off.

The messages sent out were:

  • 22:47: “Radiation threat. Radiation threat declared in Kyiv.”

  • 22:48: “Hi! There will be a nuclear alert across Ukraine. Don’t worry, it’s Oreshnik flying” [This message was written in Russia]

  • 22:49: “Chemical threat. There is a threat of a chemical attack on Kyiv. Don’t go outside.”

  • 22:49: “Street fighting threat. Street fighting is taking place in Kyiv. Don’t go outside.”

  • 23:53: An all clear is sent out

Ukrainian authorities within the hour had publicised messages on Telegram saying they believed the app system had been compromised.

The air raid alert channel said “unauthorised parties” had interfered with the system, which had been temporarily taken off line. It urged users to not click on links in “suspicious notifications”.

The Air Force wrote on Telegram: “The Air Alarm application has probably been subjected to hostile interference. There is no radiation threat! Stay calm and follow our updates on our channel.”

Russia resumes attacks, with fortified positions, after Oleshky ceasefire

The fake nuclear threats to Ukraine came as Russia resumed its attacks on the southern city of Kherson, just hours after the end of a ceasefire during which hundreds of people were evacuated from the nearby Kremlin-controlled town of Oleshky.

Kherson’s military administration said a Russian drone hit a hospital at 7.40am. Video footage showed wrecked rooms, with windows blown out, doors broken, and debris on the street. Nobody was hurt, officials said.

There is evidence that the Russian army used the six-day ceasefire to strengthen its positions in Oleskhy and to rotate in new troops. Bodies of dead civilians were also removed from a hospital morgue.

Footage shared with Sky News showed Russian soldiers deploying heavy military equipment and delivering ammunition. They carried large bags into burned out houses and buildings and disappeared into basements, the broadcaster reported.

Armoured vehicles were spotted moving around Oleshky’s streets. The occupied city is 3 miles from Kherson, on the opposite bank of the Dnipro River. Before last week’s truce, resupply was difficult because of the threat from Ukrainian kamikaze drones.

According to the commander of Ukraine’s 34th Separate Marine Brigade, Dmitry Pulinets, Russian soldiers were previously unable to drive in the city, “neither during the day, nor at night, nor in bad weather”.

“Now they have this opportunity. And for the last few days this movement has been happening constantly,” he told Sky News.

The ceasefire expired at 11pm on Sunday. Both sides hailed the local pause in the fighting – the most significant since 2022 – as a success. Ukraine’s ombudsman, Dmytro Lubinets, who visited Oleshky to coordinate the mission, said it could be repeated on other parts of the frontline.

However, Vladimir Putin’s spokesperson Dmitry Peskov said on Monday there were no plans for another truce elsewhere. He said it was “standard practice” for army units to regroup in “such circumstances” and added that he assumed Ukraine’s armed forces had “done the same”.
