I don't know much about Algerians though i do hear that they are quite aggressive people, but, what i hear from my egyptian colleagues shows that they have been a victim of media frenzy. They tell me of stories of algerians i find hard to beleive, like , 5000 prisnors were released from algerian jails, put on military plains, brought to Sudan and given knives to attack egyptian fans! And the anger at Sudan that they did not shoot the algerian hooligans!
