The United Nations Children's Fund says more than 210 million children worldwide are working full-time.

In a harsh report released by the British branch of UNICEF Monday, officials say that most of these children between the ages of five and 15 are working as slaves, miners, prostitutes and soldiers.

UNICEF maintains that the only way to end child labor is to end poverty, and is calling on wealthy industrialized nations to raise their development aid to poor countries by $50 billion.

The highest rate of child labor is in Africa where 41 percent of the children work full time. The report says Asia is next with 21 percent, followed by Latin America's 17 percent.

UNICEF stresses that not all working children are at severe risk, unless they are missing education.
