British paedophiles are paying to watch the abuse of children in the Philippines via webcams.

A BBC investigation found one British man organised the sexual abuse of five children from the same family.

Charities working in the Philippines estimate that tens of thousands of children are victims of the trade.

On Thursday, Britain's National Crime Agency will reveal how it's working with the American, Australian and Philippine police to target abusers.

A BBC team travelled to the slum of Ibabao, near Cebu City in the south of the country where police showed them a "cybersex den" where abuse is said to have happened.
