North Korea issued a warning that its revenge against the U.S. would “thousands-fold” after the United Nations imposed more sanctions on the rogue regime over its weapons programs.

“We are ready to retaliate with far bigger actions to make the U.S. pay a price for its crime against our country and people,” Pyongyang warned, the official Korean Central News Agency reported.

The U.N. Security Council on Saturday unanimously approved U.S.-drafted sanctions against North Korea worth more than $1 billion. 

Pyongyang also said a “stern action of justice” would be taken over the U.N.’s move and that it was an “outrageous delusion” to think the sanctions would change Pyongyang’s attitude.
