North Korea's leader Kim Jong-un has visited a recently remodeled facility for primary and middle school students' extracurricular activities, the North's media said Tuesday.

The leader visited the Mangyongdae Schoolchildren's Palace, a comprehensive after-school education center for school students, according to the Korean Central News Agency. It did not specify the date of his visit.

Kim ordered the remodeling of the center, which includes a gym and a swimming pool, in May last year.

The leader expressed satisfaction of the new facility, adding that students will be able to learn more about the country's revolutionary history, according to the KCNA.

At a science hall in the center, there is a model of a "Unha 3" rocket, which the North sent into orbit in December 2012, it added.

Kim's entourage included Kim Yang-gon, Pyongyang's top party official handling inter-Korean ties, and Jo Yong-won, a senior official in the North's ruling party.

Seoul's spy agency said Monday that the status of Jo is presumed to have sharply risen in the rankings of those in power in North Korea, given the frequency of his accompanying the leader on inspections. (Yonhap)
