The Democratic People's Republic of Korea is warning South Korea against its planned naval drills near their disputed sea border.
Pyongyang said on Tuesday it would take a military "physical counterattack" against the South Koean move.
The DPRK's warning was read out by the state owned television station, claiming the retaliation will be tough.
KRT Newsreader, said, "The Command of Forces of the Korean People's Army in the western sector of the front made a decisive resolution to counter the reckless naval firing projected by the group of traitors with strong physical retaliation."
The DPRK's Foreign Minister is reiterating Pyongyang's demand for peace.
Pak Ui Chun, DPRK Foreign Minister, said, "Our suggestion to sign a peace treaty was to get rid of the root of the constant threats against the region's peace and stability and to ensure permanent peace on the Korean peninsula, so as to be able to build the our economy and improve the people's lives."
South Korea's newly planned military exercise is reportedly in response to the deadly March sinking of a South Korean warship. South Korea blames the DPRK for that incident.
However, Pyongyang denies involvement and has asked to send its own investigators to examine the results of the sinking. The requests have been rejected by Seoul.
