Several North Korean soldiers captured by Ukraine die from injuries, Zelensky says.

Ukraine’s President Volodymyr Zelensky said Friday that several “seriously wounded” North Korean soldiers died from their injuries after being captured by Ukrainian forces.

“Our soldiers managed to take them prisoner. But they were very seriously wounded and could not be resuscitated,” Zelensky said in an address on Friday.

He did not specify how many soldiers had been captured. The soldiers are believed to be the first North Koreans taken as prisoners of war by Ukraine.

South Korea’s spy agency said earlier on Friday that one wounded North Korean soldier, who was captured by Ukraine, had died from his injuries, Yonhap news agency reported. CNN has reached out to South Korea’s National Intelligence Service and Ukrainian authorities for comment.
