News agency Reuters upset the organizers of the Pyeongchang Winter Olympics on Monday by publishing leaked pictures of rehearsals for the lighting of the Olympic flame.

There are strict media embargoes on the ceremonies so as not to spoil the festive spirit.

Song Seung-hwan, the creative director of the opening ceremony, said last week that spectators would be in for a surprise when they see the lighting ceremony, but now many will not.
