Six swimming world records have fallen in the first two days of competition at the Rio 2016 Olympics. Great Britain's Adam Peaty set his second world record in consecutive days, winning the men's 100 breaststroke by a huge margin of 1.56 seconds. The US men's team won the 4x100 freestyle relay. Michael Phelps, the most decorated Olympian of all time, now has 19 golds, two silvers and two bronzes.
In tennis, world number one Novak Djokovic was dumped out of Rio Games in the first round by Argentina's Juan Martin del Potro. The Serbian left the court in tears following the loss. On a day of upsets, the Murray brothers and Williams sisters also crashed out in the doubles.
After the first two days of competition, the US, China and Australia top the medals table with three golds each.
