A hard-hitting short film produced by a UK children's charity has gone viral online, racking up over 21 million views since being released on March 5.
The one and a half minute clip from Save the Children UK - entitled 'Most Shocking Second A Day Video' - depicts a year in the life of a fictional UK child, where one second equals one day.
It opens as it closes, with the unnamed girl blowing out the candles on her birthday cake - but the intervening 'year' depicts in unsettling fashion how the horrors of war unfold.
It ends with the line "Just because it isn't happening here, doesn't mean it isn't happening".
The video was made to highlight the plight of the children caught up in Syria's still-raging civil war, the third anniversary of which falls on March 15.
Some 11,000 children are estimated to have died in the conflict.
"It may not be happening here but in Syria the horror portrayed in our latest video is all too real," Save the Children said.
"Three years of civil war has devastated the lives of an entire generation of children.
"It's cost the lives of more than 11,000 children and turned more than 1 million into refugees.
"It has subjected them to trauma, indiscriminate shelling and even torture."
