Pyongyang, North Korea (CNN) -- Defying warnings from the international community, North Korea launched a long-range rocket on Friday, but it appears to have broken apart before escaping the earth's atmosphere, officials said. No element of the rocket reached space, said a U.S. official, who based that conclusion on data collected by the United States from its first few moments aloft.

The U.S. official said that, despite the launch's failure, "it will not change our response." "This was supposed to be associated with (Kim Jong Un's) ascension to power.
