South Korea's spy agency said Friday it had confirmed that a North Korean soldier sent to back Russia's war against Ukraine had been captured by Ukrainian forces.

More than 10,000 soldiers are believed to have been sent to support Russia's war against Ukraine, according to Kyiv and Seoul.

While some Western officials initially viewed the arrival of North Korean soldiers in Russia as evidence of the Kremlin’s desperation, U.S. agencies now reportedly believe the idea was North Korea’s initiative,

The soldier is believed to be the first North Korean prisoner of war captured since December, when Pyongyang deployed forces to support Russia's war in Ukraine. The confirmation comes after a photo purporting to show the wounded soldier circulated on Telegram.
