President Vladimir Putin on Friday condemned as "unfair" the IAAF decision to extend a ban on the doping-tainted Russian athletics federation from international competition.

"Of course it's unfair," Putin told journalists. "I'm assuming that we'll have a discussion with our colleagues in the world anti-doping agency and I hope a reaction from the International Olympic Committee," he said of a decision which will prevent Russian athletes from competing in the Rio Olympics in August.

The IAAF Council voted unanimously in Vienna to extend the ban on the Russian federation, but left the door ajar for some track and field stars to compete in the Rio Games as neutrals.
