Kyiv was targeted overnight by a wave of Russian ballistic missiles and drones, with explosions reported across the capital, according to the city's mayor.
Mayor Vitali Klitschko stated that a nine-story residential building collapsed in the Desnyanskyi district, trapping individuals inside. In the Holosiivskyi district, a multi-story residential building caught fire, and a hotel roof was ablaze in the central Shevchenkivskyi district. At least 11 people were injured, and residents were advised to remain in shelters.
The overnight strikes followed Ukrainian military operations targeting a large Russian oil refinery in Ufa and a military complex in the Penza region, Ukrainian President Volodymyr Zelenskyy announced earlier. The previous night, Ukraine also reportedly struck a satellite communications center in the Moscow region.
These Ukrainian actions occurred as Kyiv intensifies its campaign to pressure Russia to end the war.
Meanwhile, a new analysis from the Center for Strategic and International Studies (CSIS) estimates that total troop casualties, including killed, wounded, and missing, have surpassed 2 million. The report suggests that roughly three Russian casualties have occurred for every one Ukrainian casualty.
According to the CSIS data, Russian forces have suffered approximately 1.4 million casualties, including an estimated 450,000 deaths. Ukrainian forces have sustained between 525,000 and 625,000 casualties, with 125,000 to 150,000 deaths.
The report, which draws on data from Western governments and open sources, indicates that Russia lost territory in April and May and that 2026 has been counterproductive for the Russian military, potentially signaling that Moscow may be losing the war.
Historical comparisons cited in the report state that Russian fatalities in Ukraine exceed four times the number of all U.S. fatalities in wars combined since World War II. Additionally, Russian fatalities are more than nine times the combined total of Soviet and Russian fatalities in all wars since World War II.
The CSIS authors noted that Russian advances in key Ukrainian areas are among the slowest rates of advance seen in any war over the past century.
