North Korean leader Kim Jong Un said his nation now has a hydrogen bomb much more powerful than atomic devices it has previously detonated, according to ­reports.

In a statement from the government of the so-called “hermit kingdom,” Kim said the nation is now “a great nuclear power capable of defending the independence and national dignity of our homeland by nuclear and hydrogen strikes,” according to the RT news service.

The statement has not been independently confirmed, and the nation has not tested a hydrogen bomb.

“Kim has revealed on a number of occasions that North Korea possesses nuclear bombs. But this appears to be the first time that he talked about an H-bomb,” Chang Yong-seok, a researcher at the Seoul National University Institute for Peace and Unification Studies, told the Korea Times.

Chang, however, said he seriously questions whether Kim has a bomb many times larger than those his nation has previously tested.
