North Korea warned of 'serious consequences' after nuclear test
North Korea says it has successfully carried out its third underground nuclear test, in a widely-anticipated move set to draw international condemnation.
Pyongyang said the test involved a "miniaturised" device and was carried out in a "perfect manner".
The UN had warned of "significant consequences" if Pyongyang went ahead.
