Russia wins first gold in Rio

Mudranov is one of 271 Russian athletes competing in Brazil, despite the World Anti-Doping Agency (Wada) recommending a blanket ban after a doping scandal.

He beat reigning world champion Yeldos Smetov, who eliminated Great Britain’s Ashley McKenzie, in the final.

Meanwhile, Argentina’s Paula Pareto added the Olympic crown to her world title by winning the women’s -48kg.

Pareto, 30, beat South Korea’s Bokyeong Jeong to claim her nation’s first medal of the Games in neighbouring Brazil.

Later on Saturday, three-time European champion Mudranov won his first Olympic medal in a tight final against Smetov.

Neither man scored in the initial five-minute contest, with Mudranov eventually winning just 44 seconds into the golden score decider.
