Russian strikes across Ukraine have caused at least 15 deaths, including ten from ballistic missile impacts close to Kyiv, according to a senior national official.

Volodymyr Zelensky posted on social media that roughly 100 individuals suffered injuries in Kyiv, where rescue crews remain active at the site, while five additional fatalities occurred in the eastern city of Sloviansk.

In a separate overnight action, Ukrainian forces struck near the Russian city of Kirov more than 1,000 km (600 miles) from the front, killing six people and injuring 26 others.

Ukraine also targeted warehouses belonging to Wildberries, Russia's largest online retailer, in St Petersburg and nearby regions, triggering extensive fires.

The strikes near Kyiv appeared aimed at Defence Ministry adviser Serhiy Beskrestnov, known as Flash, along with Lyuba Shypovych, who contributed to military technology development for Ukraine.

Both individuals later used social media to confirm they remained unharmed after the incident.

Ukrainian air force spokesman Yuri Ihnat informed local television that three ballistic missiles were involved in the attack, with only one intercepted successfully.

The midday strike hit a training ground near Kyiv during a military exhibition attended by defence industry representatives.

This marks at least the third occasion since Russia's 2022 full-scale invasion that such an exhibition has come under attack.

Public reaction includes widespread criticism over holding and promoting an event of this nature.

President Zelensky noted that an investigation is underway, and Ukraine's prosecutor general is working to identify who authorized the gathering and what security protocols existed.

Drones have struck Wildberries facilities in Russia for the third time in six days, with the latest hits focused on a site near Saint Petersburg.

Earlier weekend attacks damaged two warehouses at Elektrostal east of Moscow and in Kotovsk in the Tambov region, roughly 400 km (250 miles) from the border, killing seven nightshift workers in Kotovsk and one at Elektrostal while injuring dozens and destroying goods valued at around £750m ($1bn).

These incidents have significantly affected numerous small and medium-sized Russian businesses.
