As Zimbabweans continue to wait for the result of Monday's presidential result, fake news has been circulating to fill the vacuum.

The Election Resource Centre, which says it's a non-partisan think tank on elections and democracy, says an incorrect statement alleging rigging has been circulating in its name.

On Tuesday, the opposition MDC Alliance said its candidate Nelson Chamisa won the presidential poll. His supporters and security forces clashed on Wednesday.

President Emmerson Mnangagwa has called for calm and urged people to be patient.

By law, the electoral commission has to announce the result on Saturday at the latest.
