A high-ranking military source said on Sunday that three Central African military died in a shootout between soldiers in the town of Bambari in the center of the restive country.
Three other soldiers were injured in the gunfight which broke out Saturday and pitted members of military engineering units against each other, the source said.
The altercation occurred only days after a peacekeeper died in an attack on a UN base in the CAR and a priest was burnt to death following sectarian clashes which claimed nearly 40 lives.
The volatile country, whose territory is mostly controlled by rival armed groups, has been embroiled in deadly conflict for the last six years, leading to the displacement of more than a quarter of its 4.5 million inhabitants.
