Seoul, June 30 (TIWN) North Korean leader Kim Jong-un has admitted that the detection of a "crucial case" could undermine the country's anti-epidemic efforts, state media reported on Wednesday.

Without elaborating on what the “crucial case” was, Pyongyang’s official Korean Central News Agency (KCNA) said Kim made the remarks while presiding over a politburo meeting of the ruling Workers’ Party on Tuesday.

“Senior officials in charge of important state affairs neglected the implementation of the important decisions of the party on taking organisational, institutional, material, scientific and technological measures associated with the worldwide health crisis, and thus caused a crucial case of creating a great crisis in ensuring the security of the state and safety of the people and entailed grave consequences,” Kim was quoted as saying by the KCNA.
