Zimbabwean police used teargas, water cannon and batons on Wednesday to disperse opposition youths who were demonstrating in the capital against alleged brutality by security agents.
More than 200 youths from the main opposition party, the Movement for Democratic Change (MDC), had taken to the streets two days before a planned march by all opposition parties to try to force President Robert Mugabe to implement electoral reforms ahead of the 2018 vote.
Police intercepted them and fired teargas at the protesters who were planning to hand a petition at the offices of the Ministry of Home Affairs, which is in charge of the police.
Some protesters threw back the teargas canisters, as well as rocks, toward the police, who chased them with water cannon and fired more teargas outside the MDC headquarters, forcing pedestrians and people standing in nearby bank queues to flee.
The youths had marched through the streets of the capital denouncing the police for beating up protesters and called on Mugabe to step down, accusing him of running a dictatorship.
"We have been seeing a deliberate attempt by the police to intimidate, harass and silence the people of Zimbabwe," MDC Youth Assembly secretary general Lovemore Chinoputsa told Reuters TV during the march.
Chinoputsa said police had refused to sanction the march, saying that it would degenerate into violence.
Police spokeswoman Charity Charamba said she could not immediately comment. The police routinely deny charges of brutality and instead accuse the opposition of using "hooligans" during protests to attack officers.reuters
