Report: On Wednesday, the U.S.' B-1B strategic bombers made flyovers on the Korean Peninsula and went near the military demarcation line.

It was intended to send a warning to North Korea for its repeated nuclear and missile provocations.

A day after, the general staff department of the North's Korean People’s Army issued a statement.

"The U.S. imperialist is the culprit that is pushing the situation to the imminence of a nuclear war by bringing strategic nuclear bombers on the Korean Peninsula."

The North's state-run KCTV delivered the statement, which then threatened to turn the South Korean capital Seoul into ashes with a nuclear bomb, an apparent response to the Korea Massive Punishment and Retaliation(KMPR) plan under which Seoul said it will destroy key sections of Pyongyang. 

Targeting the discussions of the 'decapitation mission' against its leadership, the North said that such an operation will lead to the destruction of South Korea's presidential office.

The North went a step further to say that it will annihilate Guam, which houses a U.S. airbase, from the face of the earth should the U.S. keep sending B-1B bombers over North Korean skies.

South Korea’s Defense Ministry said the North’s remarks are ludicrous as it comes from the very source of the initial provocation. It reiterated that North Korean provocations will be met with stern retaliation.
