North Korea launched "several short-range ballistic missiles," that landed in the Sea of Japan Tuesday morning local time, South Korea's Joint Chiefs of Staff said.
The missiles "flew approximately 250 km," the officials said.
"North Korea's missile launch is a clear provocative act that seriously threatens the peace and stability of the Korean Peninsula, and we strongly condemn it," the officials added.
Tuesday's test launches marked the second missile test of the year, following the Jan. 6 launch of an intermediate-range ballistic missile, a test that coincided with U.S. Secretary of State Antony Blinken's visit to South Korea.
North Korean leader Kim Jong Un said at the time that the "performance of our latest hypersonic intermediate-range missile system is globally significant and cannot be ignored," according to state media.

"I will refrain from making a definitive assessment at this point, but no missiles have been confirmed to have landed in our territory or exclusive economic zone, and no damage has been reported," he said.
