"It's an outrage," tweeted Emmanuel Nahshon , Israel's Foreign Ministry Spokesman. "Blatant hypocrisy. Shameful."

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.
