Ukrainian drone strikes on Russia’s Kursk region overnight sparked a fire at a nuclear plant, damaging a transformer but causing no injuries or radiation leaks, officials said.

The attack, coinciding with Ukraine’s Independence Day, also hit power facilities, while separate drone debris ignited a blaze at the Ust-Luga fuel port in Leningrad region.

Russia claimed to have intercepted 95 Ukrainian drones, while Ukraine reported downing or jamming 48 Russian drones overnight, Fox News has reported.

In a speech marking the holiday, President Volodymyr Zelenskyy vowed Ukraine would secure a “just peace” and build lasting security and strength.
