Liam Neeson has lent his face to the United Nations Children's Fund's latest campaign which aims to raise awareness of violence against children. 

The Schindler's List actor has been a UNICEF Goodwill Ambassador since 1997 and is just one of the personalities who have supported the organisation in recent years.

"Speak Out, Take Action" aims to encourage people to join the movement to fight violence against children.

UNICEF says the world needs to take "urgent collective action" with over 150 million girls and 73 million boys under the age of 18 experiencing sexual violence and exploitation.

Peter Power, Executive Director, UNICEF Ireland says “Violence destroys children and childhoods. We hope that this video will start a conversation in the home, in workplaces, in school and online about what we can do to prevent it."
