“I believe some of them have decided to return home and [Ukraine Olympic Committee President] Sergey Bubka has said he absolutely respects every individual’s right to make their own decision,” said IOC spokesman Mark Adams.

A Ukraine team official said Alpine skier Bogdana Matsotska and her father, who is also her coach, Oleg Matsotskyy, had pulled out. There was no information on whether they were actually departing the Black Sea resort, or if additional Ukrainian athletes had opted to pull out.

Ukraine team officials and some athletes held a minute’s silence in memory of the victims and black ribbons were added to Ukraine flags hanging on the balconies of their building in the athletes’ village.
