MOSCOW (REUTERS) - Russia's suspended athletics federation said on Thursday (July 2) that it had missed a July 1 deadline to pay US$5 million (S$7 million) of a fine to World Athletics. This jeopardises the chances of its track and field athletes being able to compete internationally as neutrals.

The sport's global governing body in March handed the federation a US$10 million fine for breaching anti-doping rules.

World Athletics at the time reinstated the process by which Russian athletes could apply to compete internationally as neutrals after demonstrating that they train in a doping-free environment.

It said, however, that this process would again be suspended if half of the fine was not paid by July 1.

The Russian federation told Tass agency on Thursday that the fine had not been paid as of July 2, a day after the federation's president said it did not have sufficient funds to do so.

The federation was suspended in 2015, after a report commissioned by the World Anti-Doping Agency (Wada) found evidence of mass doping among track and field athletes in the country.

Russia is also in the process of appealing against a four-year ban on its athletes competing at major international sporting events under their flag as punishment for the alteration of laboratory data.

Its case will be heard by the Lausanne-based Court of Arbitration for Sport (CAS) in November.
