The Central African Republic says its army along with Russian and Rwandan allies has recaptured the western border town of Beloko from rebels.
Several groups that have controlled most of the country for the last eight years formed an alliance in December, and started a rebellion to try to seize power.
The recapture of Beloko opens a key supply route that had been blocked since December.
Prime Minister Firmin Ngrebada said they will therefore ensure the movement of people and goods in both directions on the Bangui-Beloko axis in complete safety.
