South Korea has detected signs that North Korea is preparing to hold a major military parade and mass games performance in October as part of celebrations for the ruling party’s anniversary.

Seoul’s unification ministry cautioned at a press briefing on Thursday that the DPRK is still in the early stages of planning and that key activities are not yet visible through satellite imagery, though it said it has detected internal indications of preparations.

The ministry also revealed that North Korea is actively inviting socialist-aligned countries and various other organizations to participate in celebrations for the anniversary of the Workers’ Party
