Usain Bolt won the men's 200m to claim his second
Rio 2016 gold, his eighth at an Olympics, and keep alive his hopes of an
unprecedented 'treble treble'.
The Jamaican ran 19.78 seconds to come home ahead of
Canada's Andre de Grasse and France's Christophe Lemaitre.
Britain's Adam Gemili clocked the same time as
Lemaitre, but was denied his first Olympic medal in a photo finish.
