HARARE, Zimbabwe (AP) — Human Rights Watch says Zimbabwean security forces and unidentified gunmen have beaten and harassed dozens of people in a crackdown on the political opposition following a disputed election.

The international rights group said Tuesday that it had documented "numerous cases" of soldiers beating up people in some Harare bars and restaurants and accusing them of undermining President Emmerson Mnangagwa because most votes in the Zimbabwean capital went to the opposition.

The government denies the allegations.

The Zimbabwe Electoral Commission said Mnangagwa, who was a longtime enforcer for former leader Robert Mugabe, and the ruling party won the country's July 30 election. The main opposition party alleges that the results were rigged.

Two days after voting day, soldiers opened fire on rioters, protesters and bystanders in Harare. Six people were killed.
