Syria: The 40-second video is the latest evidence of the suffering of children during the conflict in Syria.

The clip shows the youngster singing happily as another person, presumably one of her parents, records the adorable song on camera.

Moments later a massive explosion is heard. As the blast rocks the building, the youngster is desperately picked up by the person filming, who then appears to run for cover to a more secure room.

The fate of the pair is not known, but the blast appears to subside before the end of the video.

The clip has gone viral on Facebook, where many people have expressed shock and horror at the reality of life for children in war-ravaged Syria.

Last month horrific pictures of innocent children blasted to death in Syria emerged online.

And last week, a haunting image of a small boy pulled from rubble after a bomb attack shocked the world as it highlighted the horror of war in Syria.

The little boy is thought to be one of five children injured in a military airstrike in Aleppo last Wednesday (August 17).
