Russian athletics 'tainted from the top level down'
Russian athletes are to remain banned from all international competition, including the 2016 Olympics in Rio.
Athletics chiefs have decided not to lift the suspension, which was imposed in November following accusations of state-sponsored doping.
Athletes that can prove they are clean can compete, not for Russia, but as neutrals.
Rune Andersen of the IAAF taskforce said Russia athletics "has been tainted by doping from the top level down."
