Manuel Fontaine, the regional director for the UN children's agency, says that civilians in Bangui are "under siege" and under threat from daily attacks.
Authorities said yesterday that at least nine people were killed when suspected Muslim rebels launched a grenade attack on the funeral. Witnesses said two other people died in the subsequent fighting that broke out.
Central African Republic's capital, Bangui, exploded into sectarian violence nearly four months ago. Tens of thousands of Muslims later fled the city en masse and tensions are now mounting between Christian militia fighters and regional peacekeepers.
