Berlin  - Former 100 metres world record holder Asafa Powell, Olympic 100m champion Shelly-Ann Fraser and four other Jamaican athletes did not violate the whereabouts doping rule when they didn't show up at a national team world championship training camp.

"They gave their details. We knew where they were," spokesman Nick Davies from the ruling athletics body IAAF said on Thursday.

The six athletes did attend the mandatory Jamaican training camp in southern Germany but trained in Italy.

The Jamaican athletics federation on Wednesday wanted them withdrawn from the team because they allegedly violated the whereabouts rule as the Jamaican federation had listed them as part of the training camp.

But the request was withdrawn later that day after talks with IAAF boss Lamine Diack and other officials. However, Jamaican officials did not rule out sanction after the Berlin worlds which start on Saturday and run until August 23. (dpa)
