Are Muslims involved?
The north part of the country, centered around Timbuctou, is Muslim, almost 100%. The southern part of the country, centered around Bamako (the capital), is a mix of Christian and Muslim, and is very moderate in their views.
The northern region has been stirring up problems for years now and the violence and lawlessness has creeped further and further south.
90% of the population is Muslim (mostly moderate and secular).
