Mariia Seniuk (figure skating) is Israel's flag bearer and was not greeted with cheers inside the arena.
The Italian sporting public has previously been critical of Israel's participation in sports. When the countries met in World Cup qualifiers last fall, the Italian Football Federation was fined 150,000 kronor for "violations of order and security" at the match.
The United States also drew boos and cheers as the nation marched in. However, the cheers turned into unison boos when the country's vice president, JD Vance, was shown on the arena's big screen.
Kirsty Coventry, president of the International Olympic Committee (IOC), hoped before the opening ceremony that the audience would show respect and not boo the American athletes.
"I hope the opening ceremony is seen by everyone as an opportunity to be respectful of each other," she said at a press conference ahead of the games.
The opening ceremony also takes place in Cortina, Predazzo and Livigno - reflecting the fact that these are a uniquely distributed Olympics.
Alpine star Sara Hector carried Sweden's flag in Cortina and mogul skier Walter Wallberg was the flag bearer in Livigno.
Wallberg praised himself after his efforts as a flag bearer.
"It went well, it was awesome. I give myself a five-plus. I was afraid the flag would get stuck on the pole, but it went well," he told Aftonbladet.
