Antoine Mbao Bogo with the local Red Cross said late on Tuesday that aid workers have collected 461 bodies across the capital of Bangui since Thursday.
That figure does not include the scores of Muslim victims whose bodies were brought to mosques for burial.
Muslim rebels overthrew the president of this predominantly Christian country in March, though religious motives played little role at the time. Since then, the armed Muslim fighters have been accused of carrying out atrocities against civilians and resentment toward them has grown.
Last week that pent-up rage exploded into attacks on Muslims suspected of having ties to the rebellion.
