N. Korean leader rumored on rare trip to China

SEOUL, South Korea — A special train from North Korea arrived in a Chinese border city early Saturday amid speculation of a visit to the country by Kim Jong Il, a news report said, though the reclusive leader's whereabouts remained unclear.
It was not confirmed whether Kim was aboard though he appeared to be, Yonhap news agency reported, citing an unidentified government source. The train that arrived in Dandong could also be an advance train preceding a trip by Kim, the South Korean source also was quoted as saying.
The National Intelligence Service, South Korea's main spy agency, said it was checking the report. An official in the office of President Lee Myung-bak said South Korea is closely monitoring the situation, though it has not obtained specific information. The official spoke on condition of anonymity, citing the issue's sensitivity.
