Bach says the IOC’s “thoughts and sympathy are with the Ukrainian team at what must be very difficult time.”
At least 25 people were killed and hundreds injured in clashes between police and anti-government protesters in Kiev on Tuesday.
Ukraine sent a team of 43 athletes to Sochi.
Bach says “the way they have continued to represent their nation with great dignity is a credit to them and their country.”
He says “their presence here is a symbol that sport can build bridges and help to bring people from different backgrounds together in peace.”
Earlier, the IOC rejected a request for Ukrainian athletes to wear black armbands to honor those who died.
