At least 22 people are dead after gunmen opened fire inside a hospital in the northwestern Central African Republic.
The aid group Doctors Without Borders has confirmed three of its local workers were killed during the attack Saturday at Nanga Boguila, near the C.A.R. border with Chad.
Local officials say the gunmen were members of Seleka - the Muslim rebel group that ousted the C.A.R. president last year. The officials say the rebels had come to the hospital seeking money, local village chiefs held a meeting at the site.
The Central African Republic has endured more than a year of rampant violence, much of it sectarian.
On Sunday, international peacekeepers evacuated some of the last remaining Muslims from the C.A.R. capital, Bangui. The 1,300 people had been surrounded by Christian militants for months.
Afterward, Christians looted houses and a mosque in the Muslims' former neighborhood.
Muslims have been fleeing Christian-majority areas of the C.A.R. to escape attacks by largely Christian militia known as anti-balaka.
The militias formed last year in response to a wave of killing and looting by Seleka after the group seized power.
Some 2,000 French troops and 5,000 African peacekeepers have been largely unable to halt the violence. The U.N. Security Council recently authorized a larger peacekeeping force for the troubled country.
