The South Korean military specified that they maintain full operational capability and are "in close cooperation with the United States."
According to their estimates, the projectiles fell into the sea at about 350 kilometers after rising to 30 kilometers.
NHK television channel reported, citing Japanese government sources, that the missiles fell outside Japan's exclusive economic zone.
This is the fourth launch in less than a week from North Korean territory.
Since the beginning of 2022, North Korea has conducted more than two dozen weapons tests, including the launch of the Hwasong-17 intercontinental ballistic missile, which ended the self-imposed moratorium on intercontinental ballistic and nuclear missile tests in 2017.
