Bangui - At least 16 people have been killed during clashes between rebels of the Lord's Resistance Army (LRA) and villagers in Central African Republic, a military source said late on Saturday.
LRA fighters attacked two villages in the central mining region of Bria on Thursday, initially killing six people and wounding about 10 others as they looted houses, said the source.
"The rebels were pursued and caught by villagers armed with rifles... who killed four of them," the source added.
The LRA fighters responded with a fresh attack during which they killed six more people, who they decapitated, placing their heads on tree trunks, he said.
The region has suffered regular attacks from fighters of the LRA and other rebel groups.
After the Seleka rebel coalition ousted president Francois Bozize in a March coup, interim leader Michel Djotodia vowed to put an end to LRA incursions.
The LRA, a Ugandan force set up by Joseph Kony, has killed more than 100 000 people during a reign of terror in Central Africa over the past 25 years, UN leader Ban Ki-moon said last month.
