North Korea fired several projectiles believed to be short-range surface-to-ship cruise missiles off its east coast on Thursday, South Korea's military said, according to The Associated Press.
South Korea's Joint Chiefs of Staff said in a statement quoted by the news agency that the launch came from the North Korean eastern coastal town of Wonsan. The projectiles likely flew about 200 kilometers (about 125 miles).
The statement said the launches were immediately reported to South Korean President Moon Jae-in but gave no further details.
The test is the latest provocation by North Korea, which last week fired a short-range ballistic missile that landed in Japan's maritime economic zone, prompting protest from both Tokyo and Seoul.
North Korean leader Kim Jong-Un, who personally supervised the test, later expressed conviction that the country "would make a greater leap forward in this spirit to send a bigger 'gift package' to the Yankees."
A week before that test, North Korea test-fired a medium-range ballistic missile, which it claimed was also supervised by Kim.
The West is concerned that North Korea may be on a path to developing an intercontinental ballistic missile (ICBM).
North Korea has declared that it could test-launch an ICBM “at any time” from any location set by its leader Kim Jong Un, though it remains unclear whether any of its recent tests have been of an ICBM.
