PYONGYANG - The Democratic People's Republic of Korea (DPRK) on Thursday denounced a planned nuclear security summit to be hosted by South Korea as provocation.

"The nuclear security summit, a serious criminal act and unpardonable provocation against the north, runs counter to the desire of the Koreans and the world people for peace and security on the Korean Peninsula," said DPRK's official KCNA news agency in a commentary.

The summit, scheduled for late March in Seoul, is a continuity and extension of Washington and Seoul's nuclear racket against the DPRK, it said.

It warned that the summit will only backfire and leave an adverse impact on solving the nuclear issue on the peninsula.
