Residents say armed men invaded a remote village in Central African Republic and killed six people.
The attack comes just days after rebels assaulted another nearby town, where they killed two people.
Residents in Bouca say four vehicles full of armed gunmen entered the village on Friday, where they shot six people.
Witnesses said the men did not speak Sango, the local language of Central African Republic.
Rebels overthrew the country's president in March, and for some time there have been allegations of involvement from Sudanese and Chadian fighters.
The rebels have been accused of rampant lootings, summary executions and the recruitment of child soldiers since their rebellion began in December.
Last week the United Nations envoy to the country said it "has collapsed into a state of anarchy."
