Brazil's Alan Oliveira wins gold in men's 200m race at the Paralympics, beating Oscar Pistorius of South Africa who took second.
World record holder Oscar Pistorius launched an angry attack on the International Paralympic Committee after he was beaten by Brazil's Alan Oliveira in the final of the T44 200m.
Pistorius said Oliveira's artificial legs - known as blades - are too long.
The South African was overhauled by the 20-year-old in the final 20 metres as Oliveira won in 21.45 seconds, with Pistorius second in 21.52.
"We are not running in a fair race here," Pistorius told Channel 4.
"I'm not taking away from Alan's performance but I can't compete with Alan's stride length.
"The International Paralympic Committee (IPC) have their regulations and their regulations mean that some athletes can make themselves unbelievably high - his knee heights are four inches higher than they should be.
