The strike targeted the 810th Russian Brigade, resulting in significant losses, according to Andrii Kovalenko, head of Ukraine’s counter-disinformation center.

Russia launched a New Year's Day drone strike on the Ukrainian capital Kyiv early on Wednesday, killing two people, wounding at least six others and damaging buildings in two districts, authorities said.

Something struck a group of Russian troops in Lgov, a town of 21,000 in western Russia’s Kursk Oblast, late Sunday or early Monday. “It’s terrible,” a bystander cried. “The guys are all in the bunker,” they added as the bunker burned.

Russia's losses in its invasion of Ukraine are thought to have soared in recent months while its forces have slowly advanced.
