Zimbabwe's opposition MDC Alliance says some of its activists are still missing following a crackdown by security forces in the wake of last week's election.

The party's spokesperson Nkululeko Sibanda said abductions and raids were being organised to deny the party the chance of challenging the elections results.

Six people died after MDC Alliance supporters clashed last Wednesday with soldiers, who used live bullets to disperse the crowd.

The demonstrators were angry over the delay in the releasing of the presidential election results as they suspected that the vote was being rigged.

Twenty-seven party activists have appeared in court at a bail hearing in connection with the violence.

Journalists have been tweeting from a press conference held by Mr Sibanda.

A BBC camera operator has isolated these frames that were filmed during Wednesday's trouble that show that soldiers were also using bayonets.

MDC Alliance candidate Nelson Chamisa lost the presidential election, but has alleged that the figures were massaged.

On Tuesday, he is set to reveal when he plans to go to court to challenge the results.
