The spokesman for Zimbabwe"s prime minister says Morgan Tsvangirai is asking other leaders in the region to «rescue» the unity government from which he temporarily withdrew last week, AP reported. James Maridadi said Tsvangirai was leaving later Monday to visit Congo, Mozambique, Angola and South Africa to seek «understanding and rescue.» Congo chairs the regional group that mediated Zimbabwe"s unity government agreement, and the others are key players in the group. Tsvangirai announced Friday he was withdrawing from the coalition at least temporarily, citing the prosecution of one of his top aides. Robert Mugabe"s spokesman George Charamba on Sunday said the president was too busy to address the crisis in his unity government. --SPA
