Chad has accused the Central Africa Republic army of killing six of its soldiers on Sunday.
Chad says five of them were abducted and executed, after an attack on a border post in Chadian territory.
The Central African Republic frequently accused Chad of supporting Central African armed rebel groups in its territory.
According to Chad Foreign Minister Mahamat Zene the soldiers were killed during a confrontation between CAR soldiers and a militia group by the name Ali Darassa’s Unité pour la Paix en Centrafrique near the border with Chad.
Authorities from the Central African Republic have not yet commented on the attack.
The government in the CAR capital, Bangui, often accuses Chad of trying to destabilise the country by supporting rebels.
Chad is now calling upon the international community to intervene in this alleged perpetration.
