Football Association Wales tackles abuse of young players

A campaign to stop parents and spectators shouting at children from the touchlines has been launched by the Football Association of Wales.
It says children as young as five are verbally abused, causing a growing number of youngsters to quit sport.
Wales manager Chris Coleman said children "need to be supported and encouraged from the touchline".
Sport minister John Griffiths will add his support by attending the Behind the Line, Behind the Team campaign launch in Cardiff.
Radio Wales reporter Stephen Fairclough asked people in Aberdare about their experience of the behaviour of supporters at young people's sports matches.
