Somalia is on the brink of famine. That's the dire warning from the United Nations Humanitarian Coordinator for Somalia. The UN says urgent international action is needed. Severe drought has wiped out crops and killed livestock in the worst affected areas. Communities are reportedly being forced to sell their assets and borrow food and money to survive. The UN says the number of people needing assistance has been rising rapidly. In September 5 million people needed aid. Now, that figure has risen to more than 6 point 2 million. The UN says famine can be avoided, though, with a rapid response from the international community.
