North Korean government officials said on its national television that the government has successfully tested a "miniaturized" hydrogen bomb, as the claim is being verified by experts around the world.

Seismic activity of the bomb was caught by monitoring stations in different continents at about 1:30 AM UTC, which tracked the source to North Korea.

The US Geological Survey put the magnitude of the artificial earthquake at 5.1, which is almost of the same intensity as the country's last nuclear test in 2013.

The world powers are skeptical that it was indeed a hydrogen bomb and not an atomic bomb, because of the state's tendency to misstate accurate facts about the happenings in the country.

Hydrogen bombs are different from atomic bombs, as the latter use the process of fission, which is splitting of a heavy radioactive atom such as plutonium or uranium. On the other hand, H-bombs release energy by the process of fusion, which makes them hundreds of times more potent than A-bombs.

The claim of H-bomb testing by North Korea led its southern partner to resume the broadcast of anti-Pyongyang propaganda on loudspeakers along its borders, which often includes informing its neighboring citizens of the better life in South Korea, how defectors welcomed, as well as a providing a sneak-peak into the country's soap operas and K-pop.

US President Barack Obama condemned the nuclear bomb test in his communications with South Korea and Japan, and assured the leaders that the US stands with the countries in developing a "united and strong international response to North Korea's latest reckless behavior," according to a statement released by the White House.

The United Nations Security Council termed the H-bomb tests as a violation of security council resolutions, and called it "a clear threat to international peace and security."

China opposed the new move by its northeastern neighbor, and its national media published editorials specifying why the H-bomb testing by the closed nation will have debilitating effect on its life as a nation.

"That nuclear weapons mean everything is an outdated mentality and does not fit a globalized world," an editorial in the Global Times read.

"If Pyongyang is determined to develop its economy, it should engage with the outside world, including the West. Nuclear weapons are not the solution to its domestic woes," the editorial continues. "This new nuclear test may inspire North Korea in the short-term. But it will generate more pressure from the UN and more sanctions imposed by the international community. The international environment for North Korea will deteriorate, and the internal driving forces for economic development are limited."

"If North Korea keeps doing such tests, it will hurt social stability in these Chinese regions, posing a big challenge to the Chinese government. Pyongyang must consider the long-term negative impact on Beijing-Pyongyang ties and its own development," it said.
