North Korean leader Kim Jong Un’s body “completely withered away” as he “suffered” for the people during a busy year solving the nation’s problems in 2021, a new state TV documentary said Tuesday, showing Kim struggling to walk down a set of stairs.

The documentary, titled “2021, A Great Victorious Year,” appeared to use concerns about Kim’s health stemming from his sudden weight loss to boost his cult of personality. It also showed Kim riding horses with military officials last summer and conducting other previously unseen activities, in a point of contrast to his infrequent public appearances during the year.
