Zimbabwe election: Troops shots at supporters, two killed
At least two people have been shot dead when troops opened fire in Zimbabwe's capital Harare after opposition supporters went on the rampage.
According to a BBC report, the MDC Alliance alleges the ruling Zanu-PF party has rigged Monday's presidential and parliamentary vote.
Parliamentary results show the ruling Zanu-PF party heading for a big majority but the presidential result has yet to be declared.
European Union poll monitors have expressed concern over the length of time it is taking to declare the presidential result.
The election is the first elections since long-serving ruler Robert Mugabe was ousted from power.
Report says Wednesday's violence is confined to the centre of Harare - an opposition stronghold - while other parts of the country remain calm. Latest reports from the capital suggest the security forces are in control of the streets.
MDC Alliance supporters had been gathering in various parts of Harare since the morning, but when news came that Zanu-PF had won the majority of seats in parliament and that the presidential results were not ready, the previously upbeat mood changed.
Opposition supporters went on the rampage down Harare's busy streets, heading towards an old Zanu-PF office and carrying large stones, sticks and anything else they could grab along the way. The crowd chanted: "We want Chamisa."
They believe the election has been stolen, and are demanding the MDC be announced as the winner.
Riot police using water cannon and tear gas arrived to a chaotic scene of burning tyres and an unrelenting crowd. There were hundreds of them. They jeered and pelted the police vans with stones.
In another part of the city where more opposition protesters had gathered, the army used whips to disperse them.
So far, the Zimbabwe Electoral Commission (Zec) has announced 122 seats for Zanu-PF, and 53 for MDC Alliance, ZBC state media reported. There are 210 seats in the National Assembly's lower house.
More than five million people were registered to vote, and there was a high turnout of 70%.
State broadcaster ZBC had reported that the electoral commission would announce the presidential results at 12:30 local time (10:30 GMT), but only parliamentary results were read out.
The BBC's Shingai Nyoka reports that the announcement on the presidential poll was not made because representatives of some of the 23 candidates had failed to turn up to verify the results.
A presidential candidate needs more than 50% of the vote to win outright. Otherwise, a run-off election will be held on 8 September.
A preliminary report by the Southern African Development Community (Sadc) observers said the elections were largely peaceful and conducted in accordance with the law.
The Zimbabwe's main opposition has said Mr Chamisa won the presidential election, sparking street celebrations by supporters on Tuesday.
The MDC Alliance said the ruling Zanu-PF party was attempting to rig the vote to allow President Mnangagwa to win, and the delay in releasing official results was unacceptable.
