Harare - The US Embassy in Harare said it was "deeply concerned" by the violence that erupted in Zimbabwe's capital as the country awaits final results in a disputed election.

"We urge leaders of all parties to call for calm from members of their respective parties. We further urge the Defense Forces of Zimbabwe to use restraint in dispersing protesters," an embassy statement said.

"Zimbabwe has an historic opportunity to move the country towards a brighter future for all citizens. Violence cannot be part of that process."

Violence broke out on the streets of Harare on Wednesday as security forces fired live rounds at opposition supporters protesting election results that they say were rigged. 

An opposition official told dpa three people died.
