Zimbabwe's opposition said on Friday more than 100 of its supporters had been killed and 1,500 arrested in a crackdown by supporters of President Robert Mugabe.
The Movement for Democratic Change (MDC) raised the death toll amongst its supporters since the first round of elections in March to 103 from the previous 86.
Those arrested included 20 legislators or parliamentary candidates. The MDC said in a statement that 5,000 supporters, including polling agents and candidates for local councils, were missing.
The MDC won the March polls but its leader, Morgan Tsvangirai, fell short of the majority needed for outright victory. He pulled out before the second round of the presidential election on June 27, in which Mugabe was re-elected.
