In what appeared to be a technical hitch during the opening ceremony at the Winter Olympics in the Russian city of Sochi on Friday, one of the five rings that make up the Games' symbol failed to open.
The apparent failure meant the ring could not be illuminated by fireworks as had happened during rehearsals.
Five giant snowflake-shaped structures suspended from the roof of the Fisht Stadium on the shores of the Black Sea in Sochi were supposed to open into circles and then light up with pyrotechnics.
Only four opened, and that particular feature, near the very start of the 2-1/2-hour opening ceremony, was abandoned.
Russian President Vladimir Putin has staked his reputation on staging a safe and successful Games, despite threats from Islamist militants to disrupt them.
