North Korea, which has been named as the one responsible for the massive cyber-attack targeting Sony Pictures Entertainment, is now threatening to attack the U.S. and claims that the country is behind the making of "The Interview", a satire centering on the assassination of Kim Jong-un. The threat was mentioned in a statement by the National Defense Commission on Korean Central News Agency on Sunday, December 21.

"The DPRK has already launched the toughest counteraction. Nothing is more serious miscalculation than guessing that just a single movie production company is the target of this counteraction. Our target is all the citadels of the U.S. imperialists who earned the bitterest grudge of all Koreans," it read, as translated by CNN.

"Our toughest counteraction will be boldly taken against the White House, the Pentagon and the whole U.S. mainland, the cesspool of terrorism," it continued. "The DPRK has clear evidence that the U.S. administration was deeply involved in the making of such dishonest reactionary movie."

Back on Friday, North Korea denied that they were involved in the cyber attack after officials named them as the one behind the hack. In response, the country demanded a joint probe and promised "grave consequences" if the U.S. did not comply.

In an interview with CNN, broadcast on Sunday, President Obama called the Sony hack a "cybervandalism" and did not consider it as an act of war. "We're going to review those [issues] through a process that's already in place," he said. "I'll wait to review what the findings are."
