'Beaten and shot by Zimbabwe's police'
Zimbabwe's security forces have been accused of using systematic torture to crack down on protesters.
Unrest broke out more than a week ago following a sharp rise in fuel prices.
A government spokesman defended the crackdown, telling the BBC: "When things get out of hand, a bit of firmness is needed."
Burials have been held for some of the people killed and some of the injured are receiving treatment for gunshot wounds in hospitals.
