Just in June, Algerians suffered a string of five terrorist attacks over the course of one week. Today, they suffered two attacks in two days - a suicide bomber and car bombs left some 55 dead and almost as many injured.

The attacks have again rattled Algerian security, and again, most fingers have been pointed squarely at Al Qaeda in the Islamic Maghreb.

This is happening while the United States lays claim to defeating al Qaeda in Iraq and putting it on the defensive in the rest of the world.

So do al Qaeda's attacks in Algeria disprove that claim? or do they show Algeria is simply the exception to the rule? That's one of the questions put to our panel in a deabte over who and what's behind the attacks in Algeria, and the potential consequences.
