North Korea has replaced its top officials in charge of guarding leader Kim Jong-un in recent years, Seoul's unification ministry said Tuesday.

Axar.az reports, citing Yonhap, North Korea has changed the chiefs of three major North Korean units defending the security of the North's leader -- the Guard Office of the ruling party, the Guard Department of the State Affairs Commission and the Guard Command -- the ministry said in its analysis of the major reshuffle of North Korean officials in 2025.

The ministry did not disclose the exact timing or the reason for the replacement, but it said the changed chiefs of such agencies were detected during a military parade marking the 80th founding anniversary of the Workers' Party of Korea (WPK) in October 2025.

"It is noticeable that North Korea has replaced officials in charge of guarding the 'supreme leader' in a relatively short period of time," a ministry official said.
