The call for the referendum was strongly contested by the political opposition, leading to several deaths at various protests in the streets of the capital, Brazzaville, during the week of the October 25 referendum. 
Kura hiyo ya maoni ilipigwa vikali na vyama vya upinzani nchini humo na kusababisha vifo kadhaa katika maandamano yaliyoendelea kwenye baadhi ya mitaa ya makao makuu ya nchi hiyo, Brazzaville, wakati wa juma la kuelekea kura hiyo iliyofanyika Oktoba 25.
