ZIMBABWE, Aug. 3 (CGTN) -- Zimbabwe's President Emmerson Dambudzo Mnangagwa narrowly won the country's landmark election, an outcome set to fuel fraud allegations as security forces patrol the streets to prevent protests.

Mnangagwa won 50.8 percent of the vote, ahead of Nelson Chamisa of the opposition Movement for Democratic Change (MDC) party on 44.3 percent, the Zimbabwe Electoral Commission (ZEC) said.

"Mnangagwa, Emmerson Dambudzo, of ZANU-PF party, is therefore duly declared elected president of the Republic of Zimbabwe," said ZEC chair Priscilla Chigumba.

Mnangagwa needed over 50 percent of the vote to secure victory without a second-round run-off.

Moments before the official announcement, MDC spokesman Morgan Komichi denounced the results as "fake" after he took to stage at the ZEC results center.

Six people were killed on Wednesday when troops fired live rounds against MDC demonstrators alleging the vote had been rigged.

Soldiers and police cleared central Harare on Thursday, shouting at pedestrians and traders to leave the area, as the MDC continued to allege that ZANU-PF had stolen the election.
