Camara (left) was deemed to be disrespectful

Africa's governing football body (Caf) said the incident happened prior to Sunday's Cup of Nations match between the Group A rivals.

"Titi Camara did not respect the Tunisian national anthem while it was being played," the Caf statement said.

There was no explanation as to what the former West Ham and Liverpool striker had done to warrant the warning.

Camara has been one of Guinea's key players, with three goals to his name.

Arguably, his most important strike for the team came in the dying minutes against Tunisia.

The match ended 1-1, which was enough to see Guinea through to the last eight.

Guinea now face Mali in their quarter-final match on Saturday.
