Food will be increasingly scarce in famine-struck southern Somalia until next year's harvest, Reuters quoted the head of the United Nations refugee agency (UNHCR) as saying on Thursday. "We have not yet reached the peak of the crisis," UNHCR chief Antonio Guterres told reporters in Kenya after visiting southern Somalia and the country's capital, Mogadishu. "From the point of view of the food security of the people, obviously, as time goes by, until the next harvest is possible, the situation will become worse and worse," he said. Rains are not due in southern Somalia, the worst affected area where close to three million people are at risk of starving, until October, meaning harvest will be in early 2012.
