Minusca said it sent men to the scene of the incident in the volatile Bangui district of PK5, where eye-witnesses recounted the exchange of fire which followed the killing of Mombeka on Tuesday.
BBC Afrique quotes a Minusca spokesman, Herve Verhoosel, as saying:
At this stage, we are sad to report 11 dead, 14 missing and 14 wounded.”
Calm has now returned to Bangui as the UN and government officials continued to urge residents to avoid answering “violence by violence.”
The Central African Republic is recovering from several years of civil war and despite the presence of UN troops in the country, deadly attacks against civilians are regular.
