JOHANNESBURG, South Africa (AP) -- Zimbabwe's opposition leader says talks aimed at resolving his country's political crisis are making no progress and that former South African President Thabo Mbeki should step down as mediator.
Morgan Tsvangirai also urged the world to help stop what he called "the impending famine and plague" in Zimbabwe.
Tsvangirai says he once thought that Zimbabwe President Robert Mugabe's party was willing to compromise but that "their intransigence to date is making that appear increasingly unlikely."
The two sides agreed to form a unity government, but ongoing talks have stalled over how to divide Cabinet posts.
Tsvangirai says Mbeki's "partisan support" for Mugabe's party has made it impossible for his party to continue negotiating under his mediation.
