The 2016 summer Olympic Games have officially begun.
The spectacular four-hour-long opening ceremony in Rio de Janeiro's Maracana stadium was a celebration of Brazil's diversity set against a backdrop of samba, bossa nova and funk.
A smiling Andy Murray led Team GB in the athletes parade, while the Olympic cauldron was lit by Brazilian runner Vanderlei Cordeiro de Lima.
The athletes of the 207 teams competing in the 2016 summer Olympics have made their appearance in the Maracana stadium.
As is traditional, Greece, the home of the Olympics, came in first, their flag carried for the first time by a female athlete.
In keeping with the environmental theme, each team is to be led out by a rider on a bicycle.
The proceedings saw a joyful celebration of Brazilian diversity and Carnival traditions married with a serious environmental message.
The Olympic Games has a long history of dramatic, emotional and inspirational moments.
Some three billion people are expected to watch on TV, with 50,000 spectators, 11,000 athletes and dozens of heads of state at the stadium.
