At least 15 people have been killed in Russian attacks across Ukraine, including 10 deaths after ballistic missiles struck a drone technology exhibition near Kyiv.

The attack targeted an exhibition showcasing drone technology and was attended by members of Ukraine’s defence sector. Ukrainian President Volodymyr Zelensky said around 100 people were injured in the strike.

The exhibition highlighted Ukraine’s growing use of unmanned technology during the ongoing war, making the location a significant target amid continued military tensions.

Additional attacks were reported in other parts of Ukraine. Five people were killed by Russian glide bombs in the eastern city of Sloviansk, while military officials confirmed the deaths of two men in the northern city of Sumy.

Following the attacks, President Zelensky said Ukrainian intelligence had received information suggesting Russia could be preparing another large-scale missile attack within the next 48 hours.

Meanwhile, Ukraine carried out strikes inside Russia on Friday, killing six people and injuring 26 in the city of Kirov, according to Russian officials. Ukraine also targeted warehouses belonging to Wildberries, Russia’s largest online retailer.

After the Kyiv-area strike, there were initial concerns over the safety of several individuals connected to Ukraine’s defence technology efforts, including Defence Ministry adviser Serhiy Beskrestnov, known as Flash, and technology developer Lyuba Shypovych.

The latest attacks highlight the continued escalation of missile and drone warfare as both sides increasingly rely on advanced technology in the conflict.
