Earlier that day, fellow Israeli Gili Cohen -- bronze medalist in the women's half-lightweight division -- had also stood by solemnly as the IJF's flag was raised.
"No Israeli anthem or flag. A disgrace to the spirit of sports," posted the Embassy of Israel in the US. " A disgrace to the spirit of sports."
"It's an outrage," tweeted Emmanuel Nahshon , Israel's Foreign Ministry Spokesman. "Blatant hypocrisy. Shameful."

Principle 4 of the Olympic Charter outlines that "the practice of sport is a human right," adding "every individual must have the possibility of practicing sport, without discrimination of any kind."

Yasuhiro Yamashita, considered by many to be the greatest judoka ever, said earlier this month: "Judo is a bridge that connects the world's people, cultures and countries," adding "in this fragile world, judo gives us hope to overcome the obstacles of political tension, animosity and discrimination."
Having beaten Rashad Almashjari of the UAE in the first round of the middleweight division, a second male Israeli judoka, Tohar Butbul, beat Italian Olympic champion Fabio Basile for bronze later on Friday.
