One of special trains of North Korean leader Kim Jong-Il crossed the border with China on April 3, AFP reports referring to a South Korean governmental source. However, it is unclear whether the leader himself was on the train or it carried only the people preparing his visit.

Meanwhile, according to Central Telegraph Agency of Korea (KNCA), Kim Jong-Il accompanied by Korean Defense Minister and other high-ranking officials attended a musical in Pyongyang.

Official Democratic People's Republic of Korea keeps silent on the matter. The visit of North Korean leader will be the first to China since 2006.
