Zimbabwe police fire tear gas at opposition leaders - Reuters witness

HARARE (Reuters) - Zimbabwean police on Friday fired tear gas at opposition leaders Morgan Tsvangirai and former vice president Joice Mujuru as a protest rally against President Robert Mugabe descended into violence, a Reuters witness said. Tsvangirai and Mujuru fled the rally in their cars, the witness said. Security forces have cracked down on rising protests against Mugabe and the ruling ZANU-PF in recent months as the public vents its anger at economic mismanagement, high unemployment and chronic cash shortages.
