North Korea is having Internet connectivity problems and is blaming the United States for it, New York Times reported.

The Korean Central News Agency published the New York Time article quoted a statement.

"The United States, with its large physical size and oblivious to the shame of playing hide and seek as children with runny noses would, has begun disrupting the Internet operations of the main media outlets of our republic."

Earlier the United States government looks at the Sony cyber-attack as "serious national security matter," New York Daily News reported.

President Obama himself expressed disappointment over the cancellation saying the studio should not have backed down to the cyber attackers threats.

Obama's statement caused North Korea to release a statement calling the United States leader "a monkey" for encouraging the release the controversial film, The Interview.

"Obama always goes reckless in words and deeds like a monkey in a tropical forest," the statement said.

North Korea said that the movies release "undermine" the "dignity of the supreme leadership."

Obama's threat of retaliating "proportionally" to the attack has stirred some criticism from the home front as well.

"No, I don't think it was an act of war. I think it was an act of cyber vandalism that was very costly, very expensive. We take it very seriously. We will respond proportionately," Obama told CNN's.

North Korea insisted that they are not behind the attack. U.S. Also stated that they are not behind the disruptions.

According to a press release on The Federal Bureau of Investigation's website earlier, it says that North Korea was responsible for the cyber attack.

"As a result of our investigation, and in close collaboration with other U.S. government departments and agencies, the FBI now has enough information to conclude that the North Korean government is responsible for these actions," the statement stated.
