Today at the Olympics: Katarina Johnson-Thompson agony as GB add to gold haul

Sky Brown had earlier became Great Britain's youngest Olympic medallist, the 13-year-old claiming bronze in the women's skateboard park event at the Ariake Urban Arena.

There was also history for Hannah Mills as she became the most successful female Olympic sailor ever with gold alongside Eilidh McIntyre in the women's 470 class.

Team GB picked up more boxing medals, Ben Whittaker taking silver and super-heavyweight Frazer Clarke a bronze.

Here, the PA news agency rounds up the best of Wednesday's action and takes a look ahead to more potential medal hopes on day 13.

The heptathlon ended in bitter disappointment for Johnson-Thompson, who pulled up during the 200m and eventually withdrew from the competition because of a calf injury.

Earlier, there had been scenes of delight after Brown, who had fallen in her first two runs of the skateboard final, was successful with her last attempt and a score of 56.47 to finish on the podium as Japan took gold and silver.

Mills – one of the athletes to carry the British flag at the opening ceremony – won silver in London and gold in Rio with Saskia Clark in the same boat. A fifth-place finish in the medal race at Enoshima saw her clinch another Olympic title to add to the collection.

Over at the Kokugikan Arena, boxer Whittaker had to settle for silver in the light heavyweight division where he was beaten by Cuba's Arlen Lopez on the judges' scorecards and Clarke's bout against Bakhodir Jalolov was eventually stopped because of a worsening cut.

Elsewhere on Thursday, both Jason Kenny and Jack Carlin progressed in the men's sprint at the velodrome, as did Katy Marchant through the women's keirin repechage.

Laura Muir made it through to the 1500m final, while Andrew Pozzi progressed into the 110m hurdles final.

Britain's reign as Olympic women's hockey champions ended at the semi-final stage as Holland won 5-1.
