The United Nations Security Council has expressed concern that the Central African Republic could be destabilized by continuing violence in Darfur, Sudan and escalating tensions between Sudan and Chad.
The CAR shares its northern border with Sudan to the east and Chad to the west.
Its northern region has been beset by skirmishes between government forces and rebels. At least 33 people were killed in clashes among the groups in June.
In a report issued last week, U.N. Secretary General Kofi Annan warned that the area could attract more armed groups, mercenaries and rebels trying to destabilize governments in the region.
The U.N. report also said humanitarian conditions in the country are deteriorating while human rights violations are rising.
