Russia will miss August's World Athletics Championships in London after their doping ban was extended on Monday, world governing body president Sebastian Coe said.
Coe said Russia, whose 15-month ban from athletics was prolonged at the IAAF's Council meeting in Cap d'Ail near Monaco, could not be reintegrated into the sport before November.
Double Olympic 1500-metre champion Coe was speaking after the IAAF Council approved a taskforce's recommendation that Russia was "not ready for reinstatement".
Russia has been barred from international competition since November 2015 following a damaging report alleging that state-sponsored doping was rife in the country. The ban had already been extended in March and then June 2016, preventing Russia's athletes from competing at the Rio Olympics.
The taskforce, which was set up to oversees Russia's reintegration into international athletics, produced recommendations detailing a roadmap to reinstatement.
But while "acknowledging several positive developments" at recent meetings in Moscow with RusAF, the Russian Athletics Federation, and new Russian Sports Minister Pavel Kolobkov, the taskforce also "pointed to some negative developments" including "unhelpful public comments recently made by some Russian sporting officials".
It said that RusAF "continues to face practical and legal difficulties in enforcing provisional doping bans and there continues to be very limited testing of Russian track and field athletes at the national level as well as troubling incidents at what testing is taking place".
The roadmap to reinstatement specifies that "testing of Russian athletes must take place without further incidents or difficulties" and that RusAF takes "demonstrable objective and practical steps to cultivate the clean sport movement". (AFP)
