South Korean figure skater Kim Yuna has refused to question the judges' decisions during the women's figure skating event at the 2014 Winter Olympics in Sochi.

There have been suggestions that gold medallist Adelina Sotnikova of Russia was given more points than she should have.

"I didn't watch the skaters so I didn't know about the other scores or how they skated," the Japan Times quotes the 23-year-old as saying. "I can't do anything about this. I did all I could."

"The score is given by the judges," she said when asked about the gap in the technical marks.

"I'm not in the right position to comment on it. And my words can change nothing."

Kim won the silver medal, while Carolina Kostner of Italy clinched bronze.
