Botswana’s President, Ian Khama, says Zimbabwe’s President Robert Mugabe should quit as he has no regional diplomatic support to stay in power. Khama spoke to Reuters on the sidelines of a Bi-national Commission in Gaberone today. Meeting Khama, South Africa’s President Jacob Zuma urged all parties to ensure that peace and security are not compromised amid tensions in Zimbabwe. The Zimbabwe Defence Force says it’s made progress in what it calls the clean-up of criminal elements around President Mugabe.
