The International Olympic Committee has disqualified Syrian hurdler Ghfran Almouhamad for a violation of the anti- doping rules.

The IOC made the announcement Saturday, nearly a week after Almouhamad finished eighth in the second heat of the first round in the women's 400-meter hurdles event.

The 23-year-old had provided a urine sample on Aug. 3, two days before her race, that indicated the presence of methylhexaneamine. That result was confirmed following an analysis of her second sample.
