North Korea has tested a banned intercontinental missile (ICBM) for the first time since 2017, according to South Korea.
The missile, which fell in waters south of Japan, flew for more than an hour and reached an altitude of more than 6,000km (3,700 miles).
Japanese officials estimated it had a range of 1,100km – which meant it could theoretically reach the US.
N Korea has launched a flurry of tests in recent weeks, including some the US and South Korea said were trials of an ICBM system.
In 2017, Pyongyang put in place a moratorium on testing long-range ballistic missiles and nuclear tests, following talks with then US President Donald Trump.
But in 2020, Mr Kim announced he was no longer bound by this promise.
The UN prohibits North Korea from ballistic and nuclear weapons tests, and has imposed strict sanctions after previous tests.
