Russian high jump champion Mariya Lasitskene on Tuesday hit out at Moscow's sports officials ahead of this month's world championships in Doha, saying she will not let them stop her from going to another Olympics.
The World Anti-Doping Agency (WADA) on Monday gave Russia three weeks to explain "inconsistencies" in a cache of laboratory data handed over to investigators, raising the possibility of a fresh ban on the country in the build-up to the Tokyo Olympics.

She was barred from taking part in the 2016 Rio Olympics, and said she has "no certainty" that Russian athletes will be allowed to take part in the 2020 Tokyo Olympics.

She vowed that Russian athletes will "fully defend our rights to take part" in the Tokyo games.

In another blow on Monday, the International Association of Athletics Federations (IAAF) maintained a ban on the Russian athletics federation pending analysis of the data.
Though the Russian federation has been banned since November 2015, athletes from Russia have been competing as neutrals and 118 are due to participate in the
