North Korea's official news agency, KCNA, said the country has developed a hydrogen bomb that the country expects to put onto an intercontinental ballistic missile.

The news agency noted that the hydrogen bomb has "great destructive power" and can be detonated at high altitudes and that the country can build as many of the weapons as it wants since the components are produced in North Korea, according to Reuters. The report came Sunday, local time, adding that North Korean leader Kim Jong Un inspected the device.

No independent confirmation of the weapaon has been made as of press time.

Pyongyang continued a string of provocations in the region last week, launching a ballistic missile that flew over Japan. In the past few months it has conducted a number of missile tests -- which some experts fear show the country's growing capability of reaching U.S. targets -- and Kim's regime has repeatedly threatened the U.S. territory of Guam, an island in the Pacific.

North Korea has conducted five nuclear tests since 2006. Last month the Washington Post reported that U.S. officials concluded North Korea is able to produce a miniature nuclear bomb small enough to fit on an intercontinental ballistic missile.

President Trump, who recently tweeted "talking is not the answer" in regards to the North Korea issue, spoke with South Korean President Moon Jae-in on Friday and gave "conceptual approval of planned purchases" of military equipment, according to a White House readout of the call.
