Displaced Yemenis receive food aid from the U.N. High Commissioner for Human Rights in the southern province of Abyan. While food is available in the country, many Yemenis cannot afford to buy it. About 10 million people are going hungry, aid groups say.
Yemen has long struggled as one of the least developed countries in the world. But now, after a year of protest and unrest that saw the country's longtime dictator step down, the situation for millions of Yemenis is dire.
Aid groups say some 10 million people are now without enough food to eat, and more than 200,000 children face life-threatening levels of malnutrition.
International aid has poured into Afghanistan in recent years, but it is expected to fall sharply as NATO forces pull out. That will place great strains on the economy, and may lead skilled Afghans to leave if they can't find work. Here, street children in Kabul collect food from an aid group.

Many Afghan government programs depend on foreign aid. Here, an Afghan health worker administers a polio vaccine to a child in the western province of Herat on March 27.
