A young girl is shown in close-up blowing out candles on a birthday cake, playing dress-up and asleep peacefully in a car. Then the images become darker, showing disruption, chaos, bombs and panic as the scenes descend into a Syria-type conflict and the girl and her family are forced to flee their home in fear.
The images are from a startling new Save The Children campaign that imagines what London would be like if plunged into a conflict similar to that in Syria.
The one-and-a-half minute video was launched in the run-up to the three-year anniversary of the conflict, in which, to date, 10,000 children have lost their lives and 2.3 million people have become refugees.
It closes with the words: "Just because it isn't happening here, doesn't mean it isn't happening."
"We hope the video will resonate with members of the public, particularly those who don't know much about the situation in Syria so they can really understand the plight of innocent Syrian children," said Jake Lundi, Director of Brand and Communications at Save The Children. "The message to the public is just because it's not happening here, doesn't mean it's not happening."
