SEOUL—North Korean leader Kim Jong Un has dismissed top officials in the wake of a recent standoff with South Korea, state media reported Friday, a move that suggests the young leader holds them responsible for allowing the confrontation to nearly spin out of control.

The rival Koreas earlier this week threatened strikes against each other before agreeing on measures to reduce animosity. The standoff began after land mines that Seoul says the North planted maimed two South Korean soldiers. Seoul responded by resuming propaganda broadcasts critical of Kim’s authoritarian rule for the first time in 11 years. Pyongyang then threatened to destroy the South Korean loudspeakers, and Seoul says the rivals exchanged artillery fire at the border.

During a ruling Workers’ Party meeting, Kim hailed the agreement, which came after marathon talks, as a “crucial landmark” that put “catastrophic” inter-Korean relations back on track toward reconciliation, according to Pyongyang’s Korean Central News Agency. Kim also dismissed an unspecified number of members of the party’s Central Military Commission, which handled the standoff, a KCNA dispatch said.

It gave no reasons for the dismissals, but outside analysts said they may have been sacked because they misjudged South Korea’s strong response to the mine blasts.

North Korea is intolerant of any outside criticism of its political system and worries, analysts say, that the broadcasts heard over the border could demoralize front-line troops and residents and eventually weaken Kim’s leadership.
