But some African governments are exasperated with Mr Mugabe. Phandu Skelemani, the foreign minister of Botswana, called for a blockade on fuel supplies to Zimbabwe. He said that African countries should "tell the Zimbabweans, 'look, this is going too far, we are now saying you are on your own, you can't rely on us to help you anymore' and really start refusing to deliver those necessities which keep Mugabe in power. One of those is petrol. If you deny him petrol which is used by the armed forces, which is used by the police, I don't think he'll last two weeks."
