Seven members of Zimbabwe Prime Minister Morgan Tsvangirai's party were assaulted Friday while campaigning on the eve of a key constitutional referendum.
Sten Zvorwadza, a candidate MP for Tsvangirai's MDC, told AFP the group was canvassing in a Harare township when they were attacked by supporters of President Robert Mugabe's party.
"We went down to Mbare to put up posters to canvass for a 'yes' vote when ZANU-PF rowdy youths descended on us," he said.
"Seven of us got injured, two seriously."
Zvorwadza was hit by bottle on the neck and punched with clenched fists. He also complained of spinal pain.
A BBC crew that was filming the campaign was also punched.
Zimbabwe votes Saturday on a draft constitution that will underpin new elections to end the uneasy power-sharing arrangement between Mugabe and Tsvangirai.
