Zimbabwe riot police leave opposition briefing
Zimbabwean riot police with batons and shields are leaving after breaking up a press conference by opposition leader Nelson Chamisa, who has alleged rigging of the presidential election.
Police chased away reporters without explanation but ruling party officials are now urging reporters to attend the briefing. There is no sign of Chamisa.
Opposition supporters heckled the police as they left.
Zimbabwe's authorities on Wednesday invoked a strict security act that allows them to ban public gatherings after the military broke up opposition protests in the capital. Six people were killed.
