Delegates to a workshop held recently in the Kenyan capital, Nairobi, have highlighted concerns about how child labour is undermining efforts to achieve universal primary education. "Child labour is a major obstacle to EFA (Education for All), and the elimination of child labour is key to realising the EFA," said the World Bank’s Bob Prouty, who also told the gathering that 11 percent of children below 14 years in Africa are engaged in some form of labour.
