The United Nations is warning millions of people remain cut off from desperately needed aid in the famine-stricken Horn of Africa. The number of people fleeing their homes has rapidly declined since last month, but millions remain at risk of starvation. In a visit to the Somali capital of Mogadishu, the head of the U.N. refugee agency, António Guterres, said relief efforts are still falling short.

António Guterres: “I think it’s clear that things are scaling up, but I think it’s also clear that the dimension of the problem is out of proportion with what it has been possible to do until now. I think we all need to put together all the efforts that exist—U.N. efforts, NGOs. The whole of the international community is still far from reaching the totality of the population and the stress in Somalia, because of this combination, this deadly combination, of conflict and drought.”
