In pictures: Manila slum life

The river which runs through Tondo is a great source of entertainment for the many young people who live in the slum.

Children spend hours swimming in it, but parts of it are choked with garbage. Some of the slum dwellers, like Estella, admit that they throw throw excrement in, because they have no toilet.

The river is so polluted that the United Nations says it poses a serious risk to health.
