Olympics rocked by first major doping scandal
The Beijing Olympics have been rocked by their first major doping scandal this morning.
North Korean shooter Kim Jong-su has tested positive for a banned substance and will be stripped of his silver and bronze medals.
Meanwhile, a Vietnamese artistic gymnast, who finished outside the top three, has also failed a drugs test.
Anti-doping measures at this year's Olympics are the strictest in history, with 4,000 tests expected to take place.
