The Zimbabwe Electoral Commission's decision to delay announcing the results of the presidential race at least until Thursday - three days after the vote - seemed certain to bring more opposition anger if President Emmerson Mnangagwa is declared the victor.
Shortly after the violence erupted on Wednesday President Emmerson Mnangagwa took to Twitter, blaming the opposition for deadly violence in the capital that he said was "meant to disrupt the electoral process".
