Frederick Gore Djo Bi wrote [fr] on africavox.com about the rise of racism against black Africans in Tunisia. In his post, Bi  quotes a testimony of Fabien Siei, an Ivorian engineering student living in Tunisia since 2007 [fr]:

Not a day goes by without a black African suffering from racial abuse. The most often-used insult  is “Guira Guira,” which, according to some means in a local dialect “big monkey”. For many Tunisians, we black Africans are savages.
