Japanese wrestler Kaori Icho has become the first woman to win individual gold medals at four consecutive Olympics.

The 32-year-old beat Russia's Valeria Koblova to win the -58kg freestyle wrestling division in Rio - as she has in every Games since Athens 2004.

Ten-time world champion Icho, whose 13-year undefeated record was ended in January, trailed with five seconds remaining but snatched victory.
