A FIFA source says five North Korean players tested positive for steroids at the women's World Cup.

After two players were caught during the tournament, FIFA tested the rest of the North Korean squad and found three more tested positive, the official said, speaking on condition of anonymity because the announcement had yet to be made official.

The events represent football biggest doping scandal in 17 years at a major tournament. The last doping case at the men's World Cup was Diego Maradona, who was kicked out of the 1994 tournament in the United States after testing positive for stimulants.
