The South Korean military said it was closely tracking and monitoring the situation and maintaining a readiness posture for any North Korean provocation.
The launch was confirmed by U.S. officials. A U.S. defense official told CNN the United States tracked two ballistic missiles.
The launch came around 5:55 a.m. local time, near Sukchon county, South Pyongan province, and flew a distance of 800 kilometers, the Joint Chiefs of Staff said.
It comes one week after North Korea fired two missiles from North Hwanghae province, south of Pyongyang, toward the sea east of the Korean Peninsula, the South Korean Joint Chiefs of Staff said.
