SEOUL (Reuters) - North Korean leader Kim Jong Un is unlikely to visit Seoul in the final three weeks of this year, South Korean TV channel YTN said on Monday, citing an unidentified official in the South Korean presidential office.

There had been speculation about whether Kim would visit Seoul before the end of the year after Kim and South Korean President Moon Jae-in agreed to the trip during their September summit in Pyongyang.
