Rodong Sinmun Sunday stresses this in a signed commentary.

The recent provocation by the south Korean warmongers is part of their vicious scheme to defend the brigandish "northern limit line" by persistently letting their warships into the territorial waters of the DPRK side under the pretext of "intercepting fishing boats", the commentary points out, and says:

The south Korean authorities are now busy issuing the alert order to the entire puppet forces and examining the declaration of "posture for combined control over crisis" with the U.S. like a thief crying "Stop the thief!" This is intended to shirk off their responsibility for the serious military provocation and justify their scheme for confrontation with the DPRK and moves to ignite a war against it.

There only exists in the West Sea of Korea the extension of the military demarcation line fixed by the DPRK.

The "northern limit line" adhered to by the south Korean authorities is an illegal ghost line aimed at escalating the anti-DPRK moves and provoking a war against it.

Such moves for confrontation and war with the DPRK made by the puppet war maniacs under the pretext of "defending northern limit line" will bring nothing but shameful self-destruction to them.

The DPRK will deal a merciless military counter-attack at any provocative act of intruding into its territorial waters in the future, too.
