The Korean Central News Agency, North Korea's propaganda arm, said that that dictator Kim Jong-un inspected "an H-bomb to be loaded into [a] new ICBM" during a visit to the North's Nuclear Weapons Institute. Photos accompanied the statement showed the purported hydrogen bomb being developed in a lab.
The explosive power of the "homemade" bomb is "adjustable from tens kiloton to hundreds kiloton," KCNA said.
Aside from the factuality of the North's claim, the language in its statement seems a strong signal that Pyongyang will soon conduct another nuclear weapon test, which is crucial if North Korean scientists are to fulfill the national goal of an arsenal of viable nuclear ICBMs that can reach the U.S. mainland. There's speculation that such a test could come on or around the Sept. 9 anniversary of North Korea's national founding, something it did last year.
