Former Zimbabwean vice-president Joice Mujuru has been attacked while holding a political rally, her party says.
The opposition National People’s Party said Mrs Mujuru and several others were assaulted with rocks while campaigning in a suburb of the capital, Harare.
At least eight people are injured, a party spokesman told the BBC, but Mrs Mujuru’s injuries are not serious.
Her party alleges the attack was politically motivated, and carried out by members of the ruling Zanu-PF party.
Zimbabwe has undergone rapid political change in the past year, with the departure of former president Robert Mugabe in November, after 37 years in power.
Its new president, Emmerson Mnangagwa, has promised that elections scheduled for later this year will be fair and free from violence.
