IOC board member Gian Franco Kasper apologized Thursday for comparing a ban on Russia from the 2018 Olympics to persecution of Jews in Nazi Germany.

''It was an inappropriate and insensitive comment,'' Kasper, the long-time International Ski Federation president, said in a statement.

The 73-year-old Swiss official had been speaking on the sidelines of an IOC board meeting in 2018 host city Pyeongchang. Kasper compared a potential Olympic ban for Russia - as punishment for state-backed doping and cheating at the 2014 Sochi Games - with indiscriminate persecution by the Nazis.

''I apologize unreservedly for any offence I have caused. I am truly sorry,'' Kasper said in the statement released by the IOC.

The IOC has set up two commissions to verify evidence - detailed in investigations appointed by the World Anti-Doping Agency - of Russia's doping program before deciding on the country's Olympic participation.

Last July, the IOC board declined to impose a blanket ban on Russian teams and athletes competing at the Rio de Janeiro Olympics. Instead, the decision was left with the sports federations in a chaotic two weeks of legal debate and hearings before the games.

Kasper was not a board member at the time. He has since been promoted to represent winter sports on the IOC's policy-making committee.

The two IOC commissions, investigating claims of a Russian doping conspiracy and prosecuting disciplinary cases against individual athletes, are expected to work for several more months.
