SEOUL - Democratic People's Republic of Korea's (DPRK) military threatened Republic of Korea (ROK) and the United States on Friday with "unprecedented nuclear strikes" as it expressed anger over a report the two countries plan to prepare for possible instability in the country, a scenario it dismissed as a "pipe dream."

The DPRK routinely issues such warnings. Diplomats in ROK and the US have repeatedly called on Pyongyang to return to international negotiations aimed at ending its nuclear programs.

"Those who seek to bring down the system in the (DPRK), whether they play a main role or a passive role, will fall victim to the unprecedented nuclear strikes of the invincible army," DPRK's military said in comments carried by the official Korean Central News Agency.
