Competitors from Russia and Kenya will need to have extra checks before they are allowed to compete at Rio later this year, the International Olympic Committee (IOC) has agreed.

The Committee met on Tuesday to discuss a five-point anti-doping plan.

One of the points agreed was that "the presumption of innocence of athletes" from Russia and Kenya was "being put seriously into question" because they are non-compliant with the World Anti-Doping Code.

As a result, every international sports federation should decide the eligibility of these athletes "on an individual basis to ensure a level playing field in their sport".

The IOC also said "the absence of a positive national anti-doping test should not be considered sufficient" to prove innocence, and that additional testing systems should be taken into account when assessing the athletes.

The IOC has already banned the Russian field and track team from competing in this year's Olympics, due to state-sponsored doping.

Other points agreed during the meeting include:
