PYONGYANG, May 10 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) Thursday accused South Korea of intruding into its waters in the West Sea, warning a new skirmish can happen any time if the South fails to halt such actions immediately.

    The South Korean military has been "amassing forces in the waters off five islets in the West Sea and infiltrating warships deep into the territorial waters of the DPRK almost everyday," the Central News Agency (KCNA) quoted a DPRK Navy spokesman as saying.

    The accusation came after the DPRK Wednesday agreed to allow trains to cross the border between the two Koreas during the inter-Korean general-level officers' meeting held in the truce village of Panmunjom inside the Demilitarized Zone.

    "The situation in the West Sea of Korea is so unpredictable and serious that the third West Sea skirmish can occur there anytime due to the arrogant moves of the South Korean warlike forces," said the spokesman.

    "The South Korean warlike forces had better stop acting rashly and clearly understand that there is a limit to the patience of the DPRK side," he said.

    The DPRK's accusations have been rejected by the South Korean Defense Ministry.

    The two navies previously clashed in 1999 and 2002 around the waters of the Northern Limit Line (NLL) in the West Sea (Yellow Sea), which resulted in heavy casualties on both sides.

    The NLL was not clearly demarcated when the Korean War ended in1953. The American-led U.N. Command unilaterally delineated the NLL, but the DPRK has never recognized it.
