Algeria risk playing their upcoming home games behind closed doors if their supporters misbehave at Wednesday`s 2015 Africa Cup of Nations qualifier against Mali.
Their behaviour is very much under the spotlight after the throwing of a piece of slate at a club match hit and killed JS Kabylie`s Cameroon striker Albert Ebosse on August 23.
The threat of a home ban on fans came from the Algerian Football Federation (FAF) president Mohamed Raouraoua.
"The FAF has already taken the blame from FIFA over the anti-sporting behaviour of our fans," he said on Monday.
"Another incident in the Mali game will penalise our national team who will have to play their next few home matches without their supporters," warned Raouraoua.
He added: "I`m calling on our supporters to display fair-play against Mali so as not to bring harm to our team.
"We have to give an example and above all not to whistle during the opposing side`s national anthem."
Algeria, who lost to Germany in the World Cup last 16, won their opening game on Saturday beating Ethiopia 2-1 in Addis Ababa.
