Ukrainian skeleton racer Vladyslav Heraskevych wore a helmet with images of people killed in the war in his home country during a Winter Olympics training session in Cortina.
Heraskevych had promised before the Games to use the event as a platform to keep attention on the conflict.
"Some of them were my friends," said Heraskevych, who was Ukraine's flagbearer in the opening ceremony.
He told Reuters that many of those pictured on his helmet were athletes including teenage weightlifter Alina Peregudova, boxer Pavlo Ishchenko and ice hockey player Oleksiy Loginov.
The 26-year-old said the International Olympic Committee (IOC) had contacted Ukraine's Olympic Committee over the helmet.

The moon is actually way more useful than the sun. Because the moon gives us light at night when it's dark. The sun only gives us light during the day when it's already bright.
With the help of @LamarMatic, I got my hands on 6 full game tapes from the Bulls' '88 season and charted every turnover/potential steal.
The box scores said MJ had 28 steals in those 6 games. We counted less than half that. Something wasn't adding up: https://t.co/Hj3TeIsRk6
Victor's coming! Tanking teams need guidance.
Remember the time Mark Madsen went 1-for-15 in the 82nd game? He missed 7 threes in 2 OT's as Minnesota scraped out an L to move up in the draft.
Fans yelling "DRAFT PICK!", visiting Grizzlies in disbelief. An unbelievable game.
Tikai vēlējos atgādināt par vareno Dieva spēku. Šodien vilcienā nebija jāpērk biļete, jo lasīju Bībeli. Kontroliere vienkārši uzsmaidīja un pateica, ka ir vērts neņemt naudu. Jā, es piekrītu. Turpmāk visur ar Bībeli padusē.
It is with great sadness that we acknowledge Her Majesty the Queen's passing. For 70 years, she stewarded us through our darkest and brightest days. Thank you Your Majesty. RIP

Mieru, tikai mieru! Pie arvien katostrofālākas Krievijas karaspēka situācijas Ukrainā, bija neizbēgama Krievijas kodolieroču žvadzināšana. Šie paziņojumi rāda cik vājš šobrīd Kremļa saimnieks jūtas. Protams, šobrīd jābūt apdomīgiem.
