Russia's track and field federation has been provisionally suspended by the sport's governing body following damning allegations of state-sponsored doping.
The decision by the IAAF's ruling council will keep Russian track and field athletes out of international competition for an indefinite period - possibly including next year's Olympics in Brazil.
The vote was 22-1.

A World Anti-Doping Agency committee has found Russia's anti-doping agency non-compliant with the anti-doping code and also concluded that violations discovered on the Russian track team could be taking place in other sports.
WADA's compliance review committee looked at the report issued by an independent committee earlier this week and also gave the Russian agency, known as RUSADA, a chance to respond.
Text of the decision was provided to The Associated Press by a person with access to the findings, who was not authorized to speak publicly about them.
The committee's findings will go to the WADA foundation board, which will vote on it at its meeting next Wednesday.
If RUSADA is declared noncompliant by the full board it could, among other things, cost Russia the chance to host international events.

Russian Sports Minister Vitaly Mutko has accused the IAAF of concealing more than 150 doping cases, mostly from countries other than Russia.
He says ''the IAAF since 2008 or 2009 hid not just Russian athletes' samples but 155 cases that they then pulled out with about 15 of our athletes.''
Mutko did not clarify exactly which cases had been hidden, although he mentioned that they included Russian race walkers Olga Kaniskina and Valery Borchin.
Both of those two were banned this year for violations of the athlete biological passport system, which tracks blood values to look for signs of doping, but their cases took years to resolve.
Monday's report into Russian doping by a World Anti-Doping Agency commission said the Borchin case was ''highly suspicious'' because of ''excessive'' delays in its handling by the IAAF.

Two-time Olympic pole vault champion Yelena Isinbayeva says it would be unfair for track's governing body to ban innocent athletes.
Isinbayeva, who won gold at the 2004 Athens Olympics and the 2008 Beijing Games, wrote a letter published on the Russian track federation's website hours before the IAAF was to decide on whether to ban the country from competition.
Isinbayeva says ''all my victories are honest, `clean' and deserved. I have always followed and am following all the anti-doping rules precisely. The situation the Russian national team is in now is very sad but I ask you not to treat all the athletes in the same negative way.''
She says ''to ban innocent ... athletes from competing in international events and (the) Olympic Games in Rio is not fair.''

Senior Russian officials have been lobbying hard in recent days as they try to avoid being banned from track and field.
Track's governing body will decide Friday on whether to suspend Russia, which could lead to a possible ban from next year's Olympic track events.
The most visible lobbyist is Sports Minister Vitaly Mutko, a longtime ally of President Vladimir Putin.
On Thursday, Mutko told The Associated Press that he was in contact with IAAF President Sebastian Coe and the World Anti-Doping Agency, and he now says he will speak Friday with International Olympic Committee President Thomas Bach.
Bach also met Thursday evening in Switzerland with Russian Olympic Committee president Alexander Zhukov, who has strong political connections in Russia.

Russia is offering ''broad cooperation'' to reform its anti-doping operation as it tries to avoid a ban from Olympic track and field.
That's the message from Russian Sports Minister Vitaly Mutko ahead of a key decision Friday on whether Russia should be barred from track and field competition because of its doping scandal.
Mutko, in comments to Russia's R-Sport agency, says ''we are prepared to re-certify the laboratory, or to reform, or to create a new anti-doping organization, we're prepared for broad cooperation.''
Ahead of Friday's decision as to whether Russia should be suspended from competition, the government has adopted a conciliatory tone while remaining critical of a World Anti-Doping Agency commission's report alleging a vast state-sponsored doping program.
On Thursday, Mutko told The Associated Press that Russia has no intention of boycotting next year's Olympics even if its track team is barred.
