North Korean state media said Saturday that Pyongyang had developed a hydrogen bomb that it hopes to place on to an intercontinental ballistic missile (ICBM).

The bomb's power, which state media describes as "destructive," can be detonated at higher altitudes and gives the country the ability to produce a large number of nuclear weapons, Reuters reported.

Kim Jung-Un has reportedly inspected the weapon.

The report comes as tensions between North Korea and the U.S. have risen in recent months.

Pyongyang launched a missile over Japan last week in apparent signal to the U.S. that the country would not back down over its missiles program.

Reports emerged earlier this summer that North Korea may have the technology to place a nuclear warhead on an ICBM, moving it closer to having an ability to reach the United States with a nuclear missile.
