North Korean leader Kim Jong Un likely hosted a gathering or enjoyed luxurious amenities at his east coast Wonsan beach mansion this week around the same time he was in the area to inspect a missile test and an upgraded weapons factory, according to NK Pro analysis of satellite imagery.

Planet Labs imagery shows that one of Kim’s custom megayachts made a rare trip to his Wonsan mansion’s private beach earlier this week, where it could have been used for a party similar to others seen in the same place in the past.
