The World Day Against Child Labour is held every year on 12 June. The UN estimates that around 215 million of the world's children work, many of them full-time.

Child labourers are often not enrolled in school and have little or no time to play. Many do not receive proper nutrition or care. More than half are exposed to hazardous environments, slavery, or other forms of forced labour, illicit activities including drug trafficking and prostitution, as well as involvement in armed conflict.

IBTimesUK publishes these photos in an effort to raise awareness of the issue. Please visit the International Labour Organisation's child labour page for more info.
