The North launched the missile eastward at around 8:10 a.m. from a land-based platform, the Joint Chiefs of Staff (JCS) was quoted as saying by Yonhap without further elaboration.

"For additional information, the intelligence authorities of South Korea and the United States are conducting a detailed analysis," the JCS said in a text message sent to reporters as quoted by the news agency.

South Korea's military in cooperation with the U.S. is closely watching related North Korean movements and maintaining a readiness posture against the possibility of the North's additional launches, the JCS said.

This is the first suspected projectile launch by the country in 2022.
