A top Brazilian football club has asked its supporters and players to abandon an internet campaign encouraging them to pose as Taliban fighters and post the photos online.
The BBC reports the campaign began after the current Brazilian champions, Fluminense, were defeated in a match for the South American Copa Libertadores with a controversial late goal.
In an official statement, the club said the campaign glorifies terrorism.
Several players, including Brazilian international strike Fred, have posted photos with their faces partially covered by scarves with the club's colours.
Fluminense, who are the current Brazilian champions, are known by their fans as "a team of warriors".
