(Adds quotes from spokesman)

HARARE, April 30 (Reuters) - Zimbabwe's opposition MDC said on Wednesday 20 of its members had been killed by pro-government militias in violence since last month's elections.

MDC spokesman Nelson Chamisa said the violence had reached alarming levels and soldiers took part in attacks on party members.

"More and more people perceived to be MDC supporters continue to be beaten up resulting in over 20 MDC activists being killed in just one month," he said in a statement.

"Only over the past two days, five MDC activists have been killed by ZANU-PF militia including soldiers." (Editing by Andrew Dobbie)
