The United Nations human rights group has condemned the Chelsea soccer fans who shouted racist chants and prevented a French citizen of African descent from boarding a train before a Champions League game in Paris this week.

A video showing the incident has gained worldwide attention, and renewed calls for racism to be stamped out of the world’s most popular sport.

“In recent years we have been engaging in discussions with [football associations] about exploring ways to enhance the effort to drum racism out of football after numerous examples of racist behavior by football fans, especially inside stadiums,” said Rupert Colville, a spokesman for the United Nations High Commissioner for Human Rights, on Friday. “It is important to build on the outrage created by this snapshot of the ugly face of racism, to re-energize the effort to combat it in all its forms wherever it occurs,” he added.

The episode occurred on Tuesday in a Paris Metro station before a game between Chelsea and Paris Saint-Germain. Chelsea suspended three people from its Stamford Bridge home after the incident and called the behavior “abhorrent.”

International soccer leagues have attempted for years to counter racism evident on and off the field, with mixed success.
