According to Yonhap, it appears the launch failed.
The missile followed a successful military satellite launch earlier on Tuesday. As reported by North Korean state media, the Tuesday launch occurred at the Sohae Cosmodrome, using the Chollima-1 carrier rocket. The rocket is said to have followed its planned trajectory, placing the Malligyong-1 military reconnaissance satellite into orbit. North Korean leader Kim Jong Un reportedly oversaw the launch.
Amid enhanced US-Japan-South Korea's strategic cooperation in the Indo-Pacific, Pyongyang accuses them of increasing military tensions, pointing to large-scale exercises and more US strategic assets in the region.
A summit at Camp David in August, with President Biden, South Korean President Yoon Suk-yeol, and Japanese Prime Minister Fumio Kishida, celebrated this cooperation. However, North Korea's media threatens retaliation against any US nuclear forces in South Korea, labeling these drills as provocative acts by Washington aimed at nuclear conflict.
