Egyptian judo fighter Islam El Shehaby was loudly booed at the Rio de Janeiro Olympics after his first-round loss to Israel's fifth-ranked Or Sasson, when El Shehaby refused to shake Sasson's hand, in a major breach of judo etiquette.
Sasson defeated El Shehaby with two throws for an automatic victory, with about a minute and a half remaining in the bout. Afterwards, El Shehaby lay flat on his back for a moment before standing to take his place before Sasson, in front of the referee.
When Sasson extended his hand, El Shehaby backed away, shaking his head. The referee then called El Shehaby back to the mat and obliged to him bow; El Shehaby gave a quick nod of his head. El Shehaby refused to comment afterward. Judo players typically bow or shake hands at the beginning and end of a match, as a sign of respect in the Japanese martial art.
