President Mugabe's Government has announced that it would not allow aid agencies to distribute emergency food supplies to Zimbabweans affected by a famine. The ban will wreck a relief operation that was being mobilised by the United Nations and several international charities, including Oxfam, Western diplomats said. Nearly a million people are in dire need of food, according to a survey last month by the World Food Programme. Food stocks are expected to start running out in December and even the Government says that at least four times as many people will be affected as the famine worsens.
