Pictures: Rio day 12 - GB women make hockey final and what else happened

GB's women make it through to the Olympic hockey final for the first time ever and Mo Farah survives another stumble on the track. Here's what happened on day 12.
The Team GB women's hockey team earned a place in their first ever Olympic final. They defeated New Zealand 3-0 in their semi-final match, meaning that they're guaranteed at least a silver medal - an upgrade from the bronze they won at London 2012. Head coach Danny Kerry was delighted: "That makes us the most successful GB women's team ever at an Olympics."

Jamaica's Usain Bolt cruised into the 200m final. He ran his fastest time of the season, winning the semi-final. Adam Gemili also made it through, finishing third in his heat behind Bolt and Canada's Andre De Grasse.

GB's canoe sprinters, Jon Schofield and Liam Heath, are through to the kayak double 200m final. They powered their way to get the fastest qualifying time, finishing the race in 31.899 seconds. The pair will be hoping to upgrade the bronze they won in the event at London 2012, and they're off to a pretty good start!

Meanwhile, in the 470 sailing event, GB's women, Hannah Mills and Saskia Clark, were forced to take it easy, as poor weather delayed their final race. The pair are all but guaranteed a gold though, as long as they avoid disqualification in the final race.

Team GB's showjumpers hung on to their chance for a medal. Ben Maher on his horse Tic Tac and Nick Skelton on Big Star (pictured) both made it through to the individual final.

The USA dominated in track and field on day 12, with a clean sweep of the podium in the women's 100m hurdles. Great Britain's Cindy Ofili (pictured left) just missed out on a medal. She was in third place after the final hurdle, but was overtaken by America's Kristi Castlin in the final race to the finish. Cindy came in just 0.02 seconds behind her, to claim fourth place. Her sister Tiffany Porter took seventh place in the same race.

Mo Farah (pictured left in the shades) got off to a shaky start defending his gold title in the 5000m, narrowly avoiding another fall when another competitor stumbled. But he kept on his feet and finished third in the heat, securing his place in the final.
