It's a stern warning against North Korea, which announced on Monday that it would proceed with the launch of a long-range rocketon April 12th at 10 in the morning.
Seoul warned on the same day that it might shoot down the rocket if it strayed into South Korean territory.
A South Korean defense ministry official said that the country will "track the trajectory" of the North Korean rocket after its launch, which Pyeongyang says marks the 100th birthday of North Korea's founder, Kim Il-sung.
North Korea says the rocket launch is part of a peaceful space program, carrying an "observation" satellite, the Kwangmyongsong-3 .
Washington and Seoul, however, say the launch is meant to continue the testing of the country's long-range missiles that could be mounted with nuclear weapons.
