SEOUL/TOKYO (Reuters) - North Korea fired what might be a new model of ballistic missile on Thursday 13 April 2023, South Korea said, triggering a scare in northern Japan, where residents were told to take cover, though there turned out to be no danger.
The missile flew about 1,000 km, South Korea's military said, calling it a "grave provocation".
The missile's apogee, or maximum altitude, has not been officially disclosed, though South Korea's Yonhap news agency said it appeared to have been less than 3,000 km - far below the height of some tests last year, which topped 6,000 km.
The South Korean military said it was on high alert and coordinating closely with its main ally, the United States (US), which "strongly condemned" what the White House said in a statement was a long-range ballistic missile test.
A South Korean military official said the test apparently involved a new weapons system displayed at a recent North Korean military parades.
The military was analysing the projectile's trajectory and range and the defence ministry said it could have been a solid-fuel missile.
North Korea has been working to build more solid-fuel missiles, which are easier to store and transport, and can be launched with almost no warning or preparation time.
While North Korea has tested short-range solid-fuel missiles, it has not tested a long-range missile of that type, said Bruce Bennett, a senior defence analyst at the US-based RAND Corporation.
The missile was fired at 07:23 (00:23 CET) from near Pyongyang, South Korea's Joint Chiefs of Staff said, meaning it could have been launched from an international airport close to the capital, a major site for test-firing large missiles since 2017.
Kim Dong-yup, a former South Korean navy officer who teaches at Kyungnam University's Far East Institute, said the missile might have been an intercontinental ballistic missile that was unveiled at a February military parade and powered by a solid-fuel engine tested in December 2022.
Brief panic
The nuclear envoys of allies South Korea, the US and Japan spoke and condemned the launch, saying North Korea had constantly threatened regional peace with "unprecedented levels of provocations and menacing words", South Korea's foreign ministry said.
Japan called a National Security Council meeting in response to the launch. Its defence minister, Yasukazu Hamada, said the missile appeared to have been fired eastward at a high angle and it did not fall in Japanese territory.
Japan's coast guard said the projectile had fallen in the sea to the east of North Korea. Hamada said he could not confirm whether the missile flew over Japan's exclusive economic zone.
Japanese authorities retracted the alert for Hokkaido island when they determined that the missile would not fall nearby.
Schools in Hokkaido delayed their opening times and some train services were suspended, Japanese broadcaster NHK reported.
A student there said the alert caused momentary alarm at a train station.
"For a second in the train there was panic, but a station worker said to calm down, and people did," a student told NHK.
The launch came days after North Korean leader Kim Jong Un called for strengthening war deterrence in a "more practical and offensive" manner to counter what North Korea called moves of aggression by the US.
While condemning the latest in a string of North Korean missile tests, the US renewed its offer to open talks.
"The door has not closed on diplomacy, but Pyongyang must immediately cease its destabilising actions and instead choose diplomatic engagement," US National Security Council spokesperson Adrienne Watson said in a statement.
North Korea has criticised recent joint military exercises between US and South Korean forces as escalating tensions, stepping up its weapons tests in recent months.
