Former members of the Seleka rebel group have shot dead a Central African Republic judge and his assistant, a para-military police official has said.
"Magistrate Modeste Martineau Bria ...and his aide-de-camp were cold-bloodedly killed on Saturday night" in central Bangui, the official told AFP news agency on Sunday on condition of anonymity.
"Ex-Seleka members... sped up to them on a motorbike and opened fire," he added.
The motive for the killing is not yet known.

African nations have deployed some 2,500 troops in the country in a force that is due to increase to 4,500, but diplomats and many officials say it cannot cope with the anarchy and that UN peacekeepers may be needed.
