North Korea has conducted what it considered to be its biggest missile launch since 2017.
The weapon was apparently an intermediate range missile which reached an altitude of 2,000km before coming down in the Sea of Japan.
Japan, South Korea and the US have all condemned the launch, which is the seventh test this month.
The United Nations UN has prohibited North Korea from ballistic and nuclear weapons tests, as well as imposed strict sanctions.
However, the East Asian state regularly defies the ban, and leader Kim Jong-un has vowed to bolster his country’s defences.
Experts have suggested many reasons for the spate of launches, including political signalling of strength to global and regional powers, a desire by Kim Jong-un to pressure the US back into long-stalled nuclear talks and also the practical need to test out new engineering and military command systems.
The timing is also seen as significant, coming just before the Winter Olympics in China, and ahead of the South Korean presidential election in March.
And the tests have also surged as the faltering North Korean economy struggles under US-led sanctions, pandemic-related difficulties and decades of mismanagement.
South Korea reported that the launch took place at 07:52 local time on Sunday (22:52 GMT) off North Korea’s east coast.
Japanese and South Korean officials estimated that the missile reached an altitude of 2,000km (1240 miles) and flew for 30 minutes to a distance of 800km (500 miles).
In the meantime, US has called on North Korea to “refrain from further destabilising acts”. BBC
