The United Nations World Food Program is holding its second annual global walk against child hunger Sunday.

The WFP says 200,000 people in 90 countries will walk five kilometers to raise funds for its school feeding projects worldwide.

Among the nations where volunteers will participate are Angola, Burkina Faso, Kenya and Namibia.

The agency says 6.5 million children under the age of five die because of hunger. It also says poverty and hunger keep 100 million children out of school, with the majority girls.

The WFP says it fed more than 16 million school children in 72 countries last year. The agency says it costs them $34 a year - or just 19 cents a day - to feed a child through its programs.
