Brazilian champions Fluminense have asked fans to stop posting pictures of themselves as "Taliban warriors" after an internet campaign from their supporters went viral.
Fans of the club asked people on Twitter to post pictures with their faces covered by scarves to show off their "warrior spirit."
The campaign quickly gathered pace with even some of the team's players, including Brazilian international Fred (pictured above), getting in on the act.
Fluminense are known as "the team of warriors' and their fans launched the campaign after their lost in the first leg of their Copa Libertadores tie with Ecuadorian side Emelec.
"The intentions of those who began this movement and have joined it clash with the Taliban's image, who are terrorists and not healthy warriors. That is why Fluminense Football Club denounces this campaign," the club said in a statement.
The club went on to describe the "Be a Taliban warrior" campaign as a "call for violence".
