Thumbing their nose at weeks of international warnings, North Korea launched a test rocket early this morning. The North Korean government said the the three-stage rocket, called the Unha-3, would fly south, carrying its Kwangmyongsong-3 communications satellite.

Japanese government officials said the launch failed, with Unha-3 breaking into several pieces.
