Egyptian judoka Islam El Shehaby refused to shake the hand of Israeli opponent Ori Sasson after Sasson defeated him by ippon in their match in the first round of the men’s 100+ kilogram weight class judo competition at the Rio 2016 Olympics.

The two competed Friday afternoon, with Sasson advancing to the second and El Shehaby being eliminated from the games. After the bout was over, Sasson went in for the traditional sportsmanly handshake, but the Egyptian backed away, snubbing his opponent.

The gesture was met with boos from the crowd.
