NBC News — South Korean officials say that they've analyzed parts from North Korea's recent rocket launch. They have concluded that it was mostly built using North Korean parts and technology.
The North is banned from carrying out missile and nuclear related activities under U.N. sanctions and the Security Council is closing in on a resolution that will see it punished again for December's launch. South Korean officials also say last month's launch has put North Korea one step closer to designing a missile system capable of hitting the United States.
