SEOUL, South Korea (WKOW) -- South Korean President Lee Myung-bak is urging North Korea to cancel a planned rocket test.
He said in a news conference Sunday with President Barack Obama, North Korea's plans are a violation of U.N. resolutions.
Lee's comments came one day ahead of a two-day nuclear security summit.
Washington says North Korea's rocket launches are a cover to test delivery systems for long-range missiles it hopes to mount with nuclear weapons, that could reach Alaska.
North Korea says it will launch a satellite into space using a long-range rocket as part of celebrations marking the 100th anniversary of the April 15 birth of late President Kim Il Sung.
President Obama says "bad behavior will not be rewarded" if North Korea conducts a long-range rocket launch. The President adds, it's unclear "who is calling the shots" in North Korea.
