Brazil child prostitution alert as World Cup nears

England football players heading for the World Cup in Brazil are taking part in a high-profile campaign warning travelling fans about the dangers of so-called "sex tourism".

In Recife, a city which will host four matches during the tournament, one in four sex workers is thought to be a child.

Pregnant at 16, Anna - not her real name - has been having sex since she was 12.

She told the BBC's Wyre Davies: ''Girls here go with foreigners because they are wealthy and generous''.
