As a UNICEF UK ambassador and someone who holds the issue very close to his heart, today Robbie's raising his voice along with the charity to help make some noise for the children of Syria.
The worst winter in 10 years and exposure to unspeakable violence is leaving children cold and frightened. With heavy snows, plummeting temperatures and extremely limited food, fuel, clothing and shelter, children are freezing, traumatised and in need of our help.
The situation is so desperate that for only the second time in UNICEF history a level three emergency has been declared. Only when the focus shifts from the conflict in Syria to the humanitarian crisis caused by it will any progress be made. Today you can help achieve this by raising your own voice online.
Help spread the word by sharing this story using the icons to the left of the page. Be sure to share the appeal on your Facebook profile as well, or tweet about it, mentioning @unicef_uk and including the hashtag #childrenofsyria.
Thank you in advance to everyone who takes action.
