North Korea has carried out a third nuclear test in defiance of United Nations warnings.

The move prompted criticism from its sole major ally, China, and condemnation around the world.

The North Korean news agency said the underground test used a smaller, lighter nuclear device with greater explosive force than before.

Observers say it could take North Korea closer to building a war-head small enough to arm a long-range missile.
