Though North Korea wasn't mentioned by name, the impoverished nation's recent rocket tests cast a shadow over the nuclear proliferation summit in Seoul.

The leaders of South Korea, the United States and China issued stark warnings Tuesday about the threat of nuclear terrorism during the final day of a nuclear summit that has so far been upstaged by North Korea's long-range rocket launch plans.
Nearly 60 leaders have gathered for the two-day conference meant to find ways to keep terrorists from detonating an atomic weapon in a major city. The leaders were to release a communique Tuesday about their efforts to lock down the world's supply of nuclear material by 2014.
Much of the drama, however, has centered on North Korea's stated plans to launch a satellite on a long-range rocket around the April 15 celebration of the birthday of North Korean founder Kim Il Sung. Washington and Seoul view the launch as cover for nuclear missile development; North Korea says the satellite is part of a peaceful space program and will help in forecasting the weather.
