Human rights groups in Pakistan say the country's labour laws ignore the abuse of children who, from a young age, are working on the streets or in the homes of middle-class families.

There are an estimated 12 million child workers in Pakistan, many enduring unsafe or harsh conditions.

Last week the employers of a ten-year-old girl were arrested following her death. The police say there were indications she had been beaten.
