Each team was accompanied by a child holding a copper petal with the name of the country inscribed on it.
Some of the famous flag bearers include Usain Bolt for Jamaica, Novak Djokovich for Serbia and Sir Chris Hoy for Team GB. The athletes' parade lasted for nearly 90 minutes.
Important personalities around the world including national leaders were present in the stadium to watch the opening ceremony and the athletes' parade.
