Russia’s national airline Aeroflot was forced to cancel dozens of flights on Monday after a massive cyber attack caused the company’s computer systems to fail.

A hacking group called Silent Crow claimed responsibility for the action, alongside an outfit known as Cyber Partisans.

“We declare the successful completion of a prolonged and large-scale operation, as a result of which the internal IT infrastructure of Aeroflot was completely compromised and destroyed,” Silent Crow wrote on Telegram. “Glory to Ukraine” Long live Belarus!”

US defence company Auterion will deliver 33,000 AI-powered drone guidance kits to Ukraine under a $50m Pentagon contract, the company announced on Monday.

The kits enable manually operated strike drones to autonomously track and hit targets up to 1km away by locking onto target shapes during the final phase of flight, helping overcome growing signal jamming from both Ukraine and Russia, according to a Reuters report.

Kyiv plans to acquire 4.5 million First Person View drones in 2025 and is actively seeking tech to improve targeting and jamming resistance.

Russia’s overnight strikes on a penitentiary facility in Ukraine’s southeastern Zaporizhzhia region killed 16 people and injured at least 35, according to Ukrainian military officials and regional governor Ivan Fedorov.

Fedorov wrote on Telegram that buildings at the facility were destroyed and nearby private homes were also damaged in the attack, reported Reuters.

A Russian drone blew out the windows of a 25-storey residential building in Kyiv’s Darnytskyi district, injuring eight, including a four-year-old girl, according to Tymur Tkachenko, head of the city’s military administration.

The overnight attack also sparked a fire in Kropyvnytskyi, central Ukraine, though no injuries were reported.

Ukraine’s air force said the main target was Starokostiantyniv in western Ukraine’s Khmelnytskyi region, which is believed to host major Ukrainian airfields, arsenals, and depots. No damage or casualties were reported.

The Ukrainian military said Russia launched 324 drones, four cruise missiles, and three ballistic missiles, of which 309 drones and two missiles were downed. Fifteen drones and two missiles struck targets at three locations.

Russia’s defence ministry claimed its forces hit a Ukrainian air base and an ammunition depot containing missile stockpiles and drone components using long-range, air-launched weapons.

US president Donald Trump said he is “very disappointed” in Russia’s Vladimir Putin, and that he’s cutting Moscow’s 50-day deadline to avoid secondary sanctions on Russian oil to between 10 and 12 days from now, unless Putin brings his three-year-old war on Ukraine to an end.

The countdown for the new deadline could start “tonight or tomorrow,” according to the president.

Top of the agenda will be the steel industry, followed by Ukraine and Gaza – all issues where Sir Keir and Trump still seem far apart.

A series of Ukrainian drone attacks targeted Russia’s Rostov region, killing one person and causing a fire at a train station, local officials said, according to Reuters.

Acting governor Yuri Slyusar said on Telegram that a car was hit in the town of Salsk, which killed the driver. A separate strike sparked a fire at Salsk railway station, though no injuries were reported.

Volodymyr Zelensky said Donald Trump demonstrated a “clear stance and expressed determination” after the US president shortened his latest deadline for Russia to negotiate peace.

Trump on Monday revised his timeline to “10 or 12 days”, down from a previous 50-day deadline.

“I’m very disappointed. I’m disappointed in President Putin. Very disappointed in him. So we’re going to have to look, and I’m going to reduce that 50 days that I gave him to a lesser number,” he said.
