North Korea fired a ballistic missile over Japan and into the Pacific Friday, responding to new UN sanctions with what appeared to be its furthest-ever missile flight amid high tensions over its weapons programmes.
The launch, from near Pyongyang, came after the United Nations Security Council imposed an eighth set of measures on the isolated country following its sixth nuclear test earlier this month.
It was by far its largest to date and Pyongyang said it was a hydrogen bomb small enough to fit onto a missile.
In New York, the Security Council called an emergency meeting for later Friday.
The US Pacific Command confirmed Friday's rocket was an intermediate range ballistic missile (IRBM) and said it did not pose a threat to North America or to the US Pacific territory of Guam, which Pyongyang has threatened to bracket with "enveloping fire".
Seoul's defence ministry said it probably travelled around 3,700 kilometres and reached a maximum altitude of 770 kilometres.
