Teen figure skating sensation Kamila Valieva won a gold medal having earlier failed a drug test and Olympic officials will fight Russia’s decision to let her compete at the Winter Games, the International Testing Agency (ITA) said on Friday.

The 15-year-old’s gold medal and Olympic future now hangs in the balance as the International Olympic Committee (IOC) attempts to draw a line in the sand over Russian doping.

Russian athletes are competing at the Beijing Games without their flag and national anthem because of sanctions against Russia for previous violations.
