Most of the mayhem is in the largely Christian south and especially in and around the capital, where most of the Moslems are in the south. This all began when the capital was captured by Moslem rebels in early 2013. That was followed by rebels engaging in extensive looting and other crimes. Most of their victims were Christians. This included some deliberate attacks on churches. That resulted in Christians forming militias to fight the rebels. In the last year over 2,000 people have died, most of them in the last six months. Now the Moslems remaining in the south are arming themselves and fighting back at Christian civilians. This caused the number of refugees in and around the capital to go from 20,000 to over 200,000 in March.
The Christian militia are also angry because the peacekeepers failed to curb rebel violence against Christians last year. The general chaos of the last few months has caused over a million people (a quarter of the CAR population) to flee their homes
