MOSCOW, Jan 12 (Reuters) - North Korean leader Kim Jong-il is at present in his country and the mystery person said to have crossed into China may be a member of his family, Russia's Itar-Tass news agency said on Thursday. Tass quoted an unnamed informed source in the North Korean capital Pyongyang, where the agency has a correspondent, as saying: "The leader, as far as I know, is at present in North Korea." The source said the person who crossed the border into China two days ago was probably someone close to the North Korean leadership and hinted he could belong to Kim's family, Tass said.
