A message for peace and harmony, featuring a mythical Korean "turtle" representing longevity, set the theme as the curtain fell at the closing ceremony of the Pyeongchang Olympics on Sunday.

Athletes from the over 90 countries competing in 102 medal events across seven sports and 15 disciplines entered Pyeongchang Olympic Stadium in loosely formed groups, some waving small flags representing their countries and carrying selfie sticks, before taking seats reserved for them in the stands.

Speedskater Nao Kodaira, the gold medal winner in the women's 500 meters and silver medalist in the women's 1,000, was the flag-bearer for Japan.
