LIKE MANY boys of 17, Marcos was interested in politics. When he was not at his studies, he worked for the Pro-Democracy Party in his native Chile.
But his hopes had a price. In 1989, he was arrested and taken to a police checkpoint. A few hours later, he was dead. The official report recorded that he had committed suicide.
An autopsy found that he had died as a result of "shock, probably from an electric current". Chile's National Commission on Truth and Reconciliation concluded that he had died from torture by government agents.

This is the predicament experienced by children in nearly all the countries highlighted in The Independent's series over the last fortnight, from Afghanistan to Colombia to Rwanda to former Yugoslavia. It lies behind looming crises in Burundi and Indonesia.
To address problems of this magnitude calls for systematic international action. But what would such action …
