The 2016 Rio Olympics were declared open by Brazil's interim president Michel Temer amid a chorus of boos and jeers at Rio de Janeiro.
Brazilian marathon runner Vanderlei Cordeiro lit the Olympic cauldron on Friday to mark the start of the 2016 Games.
Cordeiro famously led the 2004 Olympic marathon in Athens before victory was snatched from him when he was attacked by a spectator. He eventually won the bronze.
Tennis star Gustavo Kuertem kicked off the cauldron relay on Friday which concluded the opening ceremony.
He handed over to 1996 Olympic basketball silver medallist Hortencia Marcari who in turn passed it to Cordeiro.
The opening ceremony was decidedly simple and low-tech, a reflection of Brazil's tough economic times. In one of the world's most unequal societies, the spectacle celebrated the culture of the favelas, the slums that hang vertiginously above the renowned beaches of Rio and ring the Maracana.

- Rose Nathike Lokonyen, carrying the flag for the refugee team

"In the past two months for sure it affected the athletes. It was a difficult situation. We were ready for the worst, the whole Russian team could have been banned, but there were reasonable people that too the right decisions. It is clear that there is a doping problem, but the clean athletes they should not suffer from that."
- Russian volleyball player Sergei Tetyukhin
"We've got some pretty cool cloaks from back home. It's pretty special to be wearing that with all the past flagbearers that have worn it before. It just brings the mana (respect) of everyone that's gone in this team before."
- New Zealand's Peter Burling
"I'm very nervous because I get sweaty palms. I have a tendency to be a bit clumsy but I'll make sure I won't let this one go."
