Angry supporters of Zimbabwean opposition leader Nelson Chamisa are roaming downtown Harare, denouncing the government after official election results showed a ruling party victory in parliament.
Protesters tore down a billboard with an image of President Emmerson Mnangagwa and his campaign slogan: "The voice of the people is the voice of God."
Riot police backed by armored vehicles with water cannon are in the area but have not moved in to break up the demonstration.
Opposition supporters also marched to and from the gates of a compound where the Zimbabwe Electoral Commission has been announcing results. Police padlocked the main gate.
The opposition alleges the vote was rigged. Results of the presidential race have not yet been announced and the electoral commission says it will update on that "sometime tomorrow.
