The Russian military had lost 62,400 soldiers in Kursk Oblast since the start of the Ukrainian army’s operation there last year, Ukraine’s General Staff said on April 26.

Of this number, 25,200 were “irreversible” losses and 36,200 were injuries, according to the statement.

“Another 983 soldiers of the (Russian) army were taken prisoner. As a result, exchanges took place, which allowed hundreds of our soldiers to return home from Russian captivity,” the General Staff said.

The statement comes as Russian authorities claimed earlier that day to have fully recaptured the territory of Kursk Oblast and confirmed the participation of North Korean troops in the campaign.
