North Korea has called the United Nations an unfair organization that represents the privileges of just a few countries, saying that the sanctions imposed on Pyongyang are a violation of its sovereignty that it will try to "hit back and crush."

"What cannot be tolerated is that resolutions have been adopted through the international stage, including the U.N. by legitimizing force and arbitrariness of certain countries," the North's foreign ministry said in a statement posted on its website.

"And such injustice has been committed in broad daylight as sanctions being imposed on victims by attackers just because they are defiant," it added.

The ministry called the U.N. sanctions on its regime a "severe violation of our sovereignty," which North Korea will not tolerate.
