South Korea's Joint Chiefs of Staff (JCS) said it detected the launch. However, it did not give further details and said that the analysis is being conducted.

The North Korean boat crossed the Northern Limit Line (NLL) in waters northeast of South Korea's Baengnyeong Island in the Yellow Sea on Saturday at 11 am (Local Time), prompting the South Korean Navy to dispatch its Chamsuri-class patrol boat, according to the Joint Chiefs of Staff (JCS).
A US B-1B strategic bomber returned to South Korea to participate in the joint military exercise on Sunday, just 16 days after its previous deployment, as Pyongyang fired yet another ballistic missile into the East Sea, Yonhap news agency reported citing the defence ministry.
According to the North's state-run media and the JCS, the most recent launches came after North Korea launched two cruise missiles on Sunday from a submarine off the coast of Sinpo in the country's east.
The missiles were launched from Chunghwa County in North Korea's North Hwanghae Province at around 8 am local time on Saturday, Yonhap said, citing the South Korean Joint Chiefs of Staff (JCS).
The spokesperson for the National Aerospace Development Administration (NADA) said that the test was conducted primarily for evaluating the capabilities of satellite photography and data transmission system and ground control system.
