un article au hazard

le fameux article :

A KCNA newsreader announced the test, saying it had "great explosive power"

North Korea has carried out its third, most powerful nuclear test despite UN warnings, and said "even stronger" action might follow.

It described the test as a "self-defensive measure" necessitated by the "continued hostility" of the US.

Its main ally, China, criticised the test, which was condemned worldwide.

Nuclear test monitors in Vienna say the underground explosion had double the force of the 2009 test, despite reportedly involving a smaller device.

If, as North Korea reports, a smaller device was tested successfully, analysts say this could take Pyongyang closer to building a warhead small enough to arm a missile.

The UN Security Council will meet at 14:00 GMT to discuss the test and its ramifications, diplomats say.

Analysis

All we know at the moment about the North Korean test is gleaned from seismic data: the event was magnitude 4.9, significantly larger than the 2006 and 2009 tests.

Learning more than that will be difficult. Monitoring stations in the region can pick up radioactive elements and particles that may - or may not - have been released from the test site; that would indicate whether the device was based on plutonium, as earlier tests, or the more worrisome uranium.

But that could take days, and may be frustrated by weather conditions; it will be virtually impossible to determine if the device was "miniaturised", as North Korea claims.

North Korea announced last month that it would conduct a third nuclear test following those in 2006 and 2009 as a response to UN sanctions that were expanded after the secretive communist state's December rocket launch, a move condemned by the UN as a banned test of missile technology.
