BANGUI, Central African Republic (AP) — The United Nations says hundreds of armed rebels have agreed to withdraw from Central African Republic's city of Bangassou which they attacked over the weekend, displacing hundreds and killing a peacekeeper at a nearby U.N. base.

U.N. Central African Republic mission spokesman Herve Verhoosel said Monday only sporadic gunfire was heard overnight.

The U.N. said in a statement Cardinal Dieudonne Nzapalainga of Bangui led negotiations with the Christian anti-Balaka rebel group. It said while they couldn't determine if the rebels had yet left, they had agreed to do so.

A Moroccan peacekeeper was killed Saturday by some 700 anti-Balaka fighters who targeted the U.N. base and Bangassou's Muslim district.

Doctors Without Borders said at least 21 people were wounded but access is needed to determine the full toll.
