The world athletics governing body IAAF has upheld its ban on Russia's track and field team for the Rio de Janeiro Olympics in August over systematic doping.

Russia was suspended from track and field by the IAAF in November after an independent report from the World Anti-Doping Agency (WADA) revealed widespread state-sponsored doping.

IAAF ruled on Friday that the country had not done enough to earn re-instatement, despite Russian officials' claims that Russia had cleaned up its anti-doping system and met all the requirements for re-admission.

"In a system that's so badly failed the athletes in Russia, that it is extremely difficult to define or have any presumption that athletes are in a safe and secure enough system for us to conclude that they are eligible for international competition," Sebastian Coe, the president of IAAF, said at a news conference in Vienna.

Following the decision, Russian President Vladimir Putin condemned the ban as unfair, saying the IAAF meted out "collective" punishment that had hurt clean athletes.

Speaking to foreign media at a late evening round-table on Friday, Putin said he would seek the intervention of WADA and the International Olympic Committee (IOC) over the decision by the IAAF.
