North Korea has fired more ballistic missiles off its east coast on Saturday - the fourth launch this week - as it continues to ratchet up tensions.
The launch comes after the navies of South Korea, the United States and Japan staged trilateral anti-submarine exercises on Friday for the first time in five years, and follows US Vice President Kamala Harris' visit to South Korea this week.
South Korea's Joint Chiefs of Staff reported the new launch while Japan's coast guard said there were at least two suspected ballistic missile tests by Pyongyang. NHK, citing a government source, said that a second missile had landed outside Japan's exclusive economic zone.
