A ground-to-ground Army Tactical Missile System (ATACMS) missile was launched at targets in the East Sea, also known as the Sea of Japan, in the early morning. Yonhap news agency reported that the militaries of South Korea and the United States fired eight surface-to-surface missiles over 10 minutes starting at 4:45 am.
