North Korea has slammed President Yoon's attendance at the NATO summit, warning that this will lead to a serious security crisis for South Korea.
The North's state media on Wednesday reported on the first-ever appearances at NATO by the South Korean and Japanese leaders.
The report called President Yoon a "human shield" for NATO.
It also said the United States is the NATO system to ostracize China, and agreed with Russia that the war in Ukrain was caused by NATO's own behavior.
