In a sense it already has escalated to actors outside the country, because we know that there are several movements involved in the occupation of the north. The first were the Tuareg fighters themselves. We also have Ansar Dine, which is a Salafist jihadist movement. We have also a breakaway movement of that called Mujao; I won't go into the details. We know that there has been support of these two by al-Qaeda in the Islamic Maghreb.
We already have heard, for example, that in the town of Timbuktu the Tuareg fighters are being kicked out by these other Islamic groups, so that is actually the most worrying sign in this whole episode: it's the grip that these other outside groups will have.
It's a complicated situation, because other countries' inclination, I should say, to intervene also depends on what the implications are for the Tuareg. Because originally it was hoped that you could actually come to a political settlement with the Tuareg, which is something that countries in the region—like Burkina Faso, like Niger—also want, because they don't want the Tuareg to be problems in their own countries.
