North Korea stepped up its counter to the United States' accusation against it of being involved in the Sony hack, and has even threatened to target the White House, the Pentagon and the whole US mainland, which it referred to as a "cesspool of terrorism".

North Korea also placed the blame for the controversial film "The Interview" on the Obama administration and called it "propaganda against North Korea".

"The DPRK (North Korea) has clear evidence that the U.S. administration was deeply involved in the making of such dishonest reactionary movie," the administration said through its official news agency, KCNA.

"The movie was conceived and produced according to the "guidelines" of the U.S. authorities who contended that such movies hurting the dignity of the DPRK supreme leadership and inciting terrorism against it would be used in an effective way as "propaganda against north Korea".

The Kim Jong-un regime sent out a stern warning through a post titled "U.S. Urged to Honestly Apologize to Mankind for Its Evil Doing before Groundlessly Pulling up Others'" in which it has lashed out against the US and unequivocally demanded an apology to all Koreans.

"The U.S. should reflect on its evil doings that put itself in such a trouble, apologize to the Koreans and other people of the world and should not dare pull up others," the release said.

North Korea described the controversial film, that is based on a comical plot to assassinate Kim Jong Un, as "undesirable" and "reactionary" and claimed that the purpose of the movie was to incite terrorism.

"The Interview is an undesirable and reactionary one justifying and inciting terrorism which should not be allowed in any country and any region... the movie is run through with a story agitating a vicious and dastardly method of assassinating a head of a legitimate sovereign state".

The North also gave out what it claimed was its toughest counteraction against the US, threatening to blow up all the US citadels, including the White House and the Pentagon.

"The army and people of the DPRK are fully ready to stand in confrontation with the U.S. in all war spaces including cyber warfare space to blow up those citadels. Our toughest counteraction will be boldly taken against the White House, the Pentagon and the whole U.S. mainland, the cesspool of terrorism, by far surpassing the "symmetric counteraction" declared by Obama," North Korea has warned.
