Zelensky warns of greater military cooperation between Moscow and Pyongyang, including sending more troops and military equipment

Despite their elite status, North Korea's "Storm" troops were ill-prepared for the war, South Korea's National Intelligence Service said.

Ukrainian President Volodymyr Zelensky confirmed Monday more than 3,000 troops from North Korea have been killed so far fighting next to Russian forces.

North Korean troops have now entered Russia’s war with Ukraine in a major way, and some have been killed, Western officials say.

"Through various sources of information and intelligence, we assess that North Korean troops who have recently engaged in combat with Ukrainian forces have suffered around 1,100 casualties," the JCS said in a statement.

South Korea's military has said that North Korea is preparing to continue aiding Russia in its war with Ukraine, despite casualties.

Pyongyang's troops fighting alongside Vladimir Putin's forces in Russia's Kursk region are being killed and injured according to the U.S.

South Korea's military said on Monday it has detected signs of North Korea preparing to send more troops and weapons, including suicide drones, to Russia to support its war against Ukraine.

There are risks of North Korea sending additional troops and military equipment to the Russian army,” Zelensky said. “We will have tangible responses to this.”

North Korean soldiers fighting for Russia were given fake military documents with Russian names and birthplaces, the Ukrainian military said, amid claims from Kyiv that Russia is trying to conceal the presence of foreign fighters on the battlefield.
