North Korea Says It Successfully Tested a Hydrogen Bomb

South Korea’s intelligence agency said a device North Korea tested on Wednesday may not have been a hydrogen nuclear bomb, its Yonhap News Agency reported.

North Korea, which is now under United Nations sanctions for its nuclear and missile programmes, has previously conducted three nuclear tests in 2006, 2009 and 2013.

However, several bomb experts have said that the explosion registered in neighbouring countries was not powerful enough to be the H-bomb which Kim Jong-un is claiming. The hydrogen bomb, also called the thermonuclear bomb, uses fusion, or atomic nuclei coming together, to produce explosive energy.

“We unequivocally condemn the behaviour of North Korea, which today claimed to have detonated a nuclear weapon”, the statement said.

According to reports, North Korea obtained “many of the designs for gas centrifuges and much of the machinery” required to make highly enriched uranium for nuclear weapons from Pakistan, which in return got ballistic-missile parts from North Korea.

Another council diplomat said the United States and Japan jointly requested the urgent council meeting.

Mr. Abe said Japan absolutely could not tolerate North Korea’s nuclear testing.

The two defence leaders reaffirmed that the worldwide community does not and will not accept North Korea as a nuclear state, and pledged that both sides would coordinate appropriate alliance responses to these provocations, Cook said.

The hydrogen bomb is in fact already the global standard for the five nations with the greatest nuclear capabilities: the U.S., Russia, France, the United Kingdom and China.

“The Democratic People’s Republic of Korea (DPRK) once again carried out the nuclear test irrespective of the global community’s opposition”.

The Foreign Secretary said he condemns without reservation the move, which the country announced in a state broadcast.

South Korean President Park Geun-hye called the test “an act that threatens our lives and future”.

(CNN)Sen. Marco Rubio was the first – and so far the only – presidential candidate to respond to reports of North Korea successfully carrying out its first hydrogen bomb test.

While a fourth nuclear test had been long expected, the timing of Wednesday’s explosion came as a surprise.

Regardless of the nature of the test, if confirmed it could strain North Korea’s relations with China, its closest ally.

Germany said it would summon North Korea’s ambassador on Wednesday, foreign ministry spokesman Martin Schaefer told a government news conference, adding the step was “a strong signal, even a protest”.

A miniaturized H-bomb can trigger a weak quake magnitude, but only the USA and Russian Federation have such H-bombs, Lee cited the NIS as saying.

I strongly urge the DPRK to implement fully all relevant resolutions of the UN Security Council and the IAEA.
