Russia is suffering nearly 2,000 casualties a day trying to recapture the Kursk region and seize ground along the main front line in eastern Ukraine, according to Kyiv’s military.

Russia suffered its deadliest day in the war Monday — losing 1,950 soldiers in a failed attempt to retake Kursk from Ukrainian troops, Kyiv officials said. The Russian forces saw their assault whipped out by Kyiv troops who continue to hold onto most of the land taken during their surprise counter-invasion in August,

Ukrainian President Volodymyr Zelensky said Monday that Russia has deployed nearly 50,000 troops to Kursk, the southern Russian region where Kyiv launched its surprise counteroffensive in the summer.

Ukraine's president says the incursion is limiting the forces Moscow can deploy inside his country.
