The sanctions were the second of their kind, following those that blacklisted leader Kim, 10 other top officials and five state agencies in July. 

"This is nothing but Washington's last resort to tarnish the image of the DPRK," the state-run (North) Korean Central News Agency said in a commentary. DPRK is the abbreviation of the North's official name - Democratic People's Republic of Korea. 

The US strategies of making a preemptive nuclear attack and slapping extreme sanctions on Pyongyang have become threats to the security of its mainland, the agency said. 

Instead of learning a lesson from the Bush administration which pushed the North to gain access to nuclear weapons, the Obama administration has persistently resorted to the worst nuclear threats and blackmail and the harshest-ever sanctions against it, the agency insisted.

In countering US hostile moves, the North has succeeded in diversifying, miniaturizing and standardizing nuclear warheads and increased the types of delivery means, the agency added. 

The US is not qualified to talk about others' human rights as it is the world's worst human rights abuser, the agency asserted.

"Obama would be well advised not to waste time taking issue with other's 'human rights issues' but make good arrangements for packing in the White House," the agency said. (Yonhap)
