Here's a special report from our Observers team who spoke to a Bishop in the town of Bossangoa, in Central African Republic's northwest region. Since Seleka rebels ousted President François Bozizé last March, security and humanitarian conditions have continued to deteriorate in the central African country. Communities in the northwest, the former president's heartland, are being terrorised by fighting between former members of the Seleka, and local militia groups made up mostly of Christian farmers. Bossangoa has been split in two: about 2,000 Muslims have taken shelter in the Liberty School in centre of the town, while 37,000 Christians have sought refuge at the Catholic Mission. Claire Williams has the story.
