North Korea fired what appears to be a single ballistic missile toward its east coast on Tuesday morning, South Korea's Joint Chiefs of Staff (JCS) said, evaluating later in the day that the missile appears to be more “advanced” than the one launched last week.

The DPRK launched the likely ballistic missile at 7:27 a.m. KST from Jagang province, from which the country launched its last two “hypersonic” missiles, according to the JCS. The projectile traveled more than 435 miles (700 km) at a maximum speed of around Mach 10, reaching an apogee of 37.3 miles (60 km).
