In the Central African Republic (CAR), at least 20 people have been killed in fighting between rival rebel groups. <br/><br/>UN peacekeepers said they had intervened to stop further violence in the northern town of Kaga Bandoro, where the killings happened. A spokesman for the presidency put the death toll at 26. <br/><br/>He said members of the mainly Muslim Seleka rebel group went from door to door and killed their victims. The CAR has been prey to sectarian violence since March 2013, when Seleka rebels briefly seized power and deposed the Christian President Francois Bozize.
